 You might have had some rounds of What we call it as Menti.com the quiz competition the leaderboard and all with yeah exactly Surya not many meter you guys were at Menti.com, right? Good so who was the winner of the competition for Mathematics Aiden very good Who was the winner for the competition of chemistry? Okay, only chem has happened by now. Okay. Okay. Okay. Okay. Okay. Got it. Got it. Got it. Got it So the chemistry one was one by Aiden. Okay. Very good. Very good. Very good. So here we are today with the round for physics How was your experience with the chem on chem on e1 for very easy e5 for very difficult So between one and five silly mistakes are beautiful Good e3 Five was difficult 3.75 Okay. Bye. Okay. Good Very good. Very good. Very good. Very good. You might have got your respective scores by now. Yes or no Okay, who think they might be in the highest Kindly drop in your scores here Whoever thinks that they might be in the highest, please drop in your scores Aiden 355. Okay. Anyone else to claim that? Aiden got 355 Shrishti 320 350 Aditya very good Very good. Very good. Very good. Very good. Very good. Very good Nice nice nice nice Okay Okay Good good good good good 342 are there 310 are there very nice very nice very nice So clap for everyone who actually even attempted it. Good. You had an experience and now let's Drive ourselves in the new experience of a Physics quiz. Okay, so go to mentee.com No problem, Surya. I am typing down the Code here clear mentee.com. Everyone know M E N T I mentee.com. Okay, please go to mentee.com Yes, yes, yes, sir, please Yeah, you just display that you know you start the presentation before starting the quiz it will be there in the Fun pages Yeah Don't start the quiz just No, actually what I was doing is I had opened the presentation so that they should not be able to see the answer So just I removed off the screen sharing So now you should be able to write visible eight nine three two nine six is the code 23 25 26 very good 27 29 30 31 32 33 34 35 36 very good 37 38 39 40 41 very good 42 very good very good very good 51 are we expecting more very good very good very good very good 54 very good very good very good 55 On the screen I'll just The code and the 9 6 it is on the screen here. It is here 58 57 58 57 58 57 58 Good good good good good good good 60 59 60 61 So like we make popcorn I'll just count for 10 seconds if no one joins then I'll trigger this Quiz right 60 60 60 61 60 61 60 61 62 Good good excellent very good very good eight seven six five four three right three five four three two one and Here we go. All right. Oh, oh, and here we go. Oh, oh and here we go And here we go one two three Good good good good Just to remind you I have given 100 seconds only instead of one 120 seconds. That is two minutes. I Guess everyone has responded 65 people have responded Because I know that as soon as everyone will respond and here is leaderboard number one 23 people answered correct out of 66 Don't scare me off guys Give the question sometime many of you I know would have just by mistake clicked on some other option I know it because I've seen your responses over charts Okay, so here is the leaderboard. Let's see who was the fastest and all that Good, Surya and the like the beauty is The least variance in this course very good very good very very very good Now you guys appear charged up and with that Here we go with the next question or Before that Repeat So can you explain the answer to the yeah, that's what I guess you guys might be looking for a Explanation right? How do you join this thing? Aditya go to menti.com Aditya, I guess you might not be yeah It might be closed off by now That's why there is I guess some importance of joining You can join join also Yes, so you can see this cream 993 296 will be the code but I guess once you log out in middle They'll allow you to join back, but if you have not joined in the first place, then it will be difficult. Okay, got it So now let's proceed with What we call it as our answers, okay? I have made a mistake for that I'll consume some odd five second of yours Okay, and here this First question. I'm sorry. I'm sorry guys. I couldn't like today. I directly created the PowerPoint presentation so couldn't arrange them fine Okay, what I'll do is guys after this after the session I'll I have other question. I could really see easily. I have other all the questions. I'm really sorry for this Okay Yeah, I'll re-explain that post finishing the question. You can go to the Mentimeter this thing is first slide you can display from there. It says only first slide first slide in the Mentimeter first on you can Yeah, here is the question, right? Right guys So now simply I'll create a word for you here only If at all it will be required simple question is via graph for parallel and series combination of two identical Resistors are as shown clear Find parallel and series. Am I clear or wrong? correct So V by I will give you the the the resistance So, you know Resistance for parallel will be lesser than resistance for Series since the lesser slope will be the answer alpha will be the answer. I hope Okay, yeah Simple good Now going on to the next question here goes the one and two and two So there's a question. What if V is on the x-axis? It will be exactly opposite then Then one by R will be there in the curve and they will have the taste here They will have that same taste here Good good good good good good good 58 59 It's really happy that in less than half the portion of time UI guys are responding right So what happens is the only thing which is worrying is the answers given in first primary five or six seconds Because that gives an idea here. These guys are not taking up this question seriously But I understand first day. I was also in a doubt, but now I have understood that Yes, you guys read half the question by the time it is being displayed on screen, right? so one and Here are the last 10 seconds 66 people have already responded. So I guess 67 have joined actually okay 68 have joined to one and time up again Got that that's why I Interfered in the Tushar sir's voice Tushar sir, please explain that what you were explaining initially, please Yeah, so actually I don't have the The paper is in the access to the tab But guys if V and IV is on the y-axis V by I is the slope of the curve, which is the resistance, right? But if you do IV it will be exactly opposite. You'll get conductance instead of resistance Theta is given here. So by calculating tan theta, which you guys have selected you are calculating I by V What sir is saying which is not resistance? What it So you have to calculate tan knowingly. I saw that Tushar sir have taught you Trignometry, that's why I kept this question 1090 minus theta is caught theta and hence your delta will be the correct answer got it Am I correct? Yes Everyone got it Yeah, see guys, I'll just draw it here simple see where you answered that There should be Right or not V I we calculate V by I we get R So for that, this is the slope like tan theta you guys might have done that trigonometry Yeah, now here. What is given? And theta is the angle over here So the required angle for us becomes 90 minus theta anyway. We have to calculate tan of Angle made with the positive direction of x-axis. So it will be caught theta and hence caught theta will give you the Simple simple everyone right Aria Good good good good. Anyway, anyway, but yeah anyway so Good, so here we go leave the question invest some time Invest the time no problem There is no point of responding in five seconds if your answer is wrong But there is pretty much points and reward pretty more points and rewards You will get if you'll respond in another three seconds eight seconds and with the correct answer, okay? shop one and two and three So, Surya lost this race Aiden Attempted to lead very good now see with the two question the second question coming into appearance There is a huge variance in this course Okay, sure so One and two and three Look, we have done this kind of question in our last Monday's exercise Attempted take time respond to responses. I received as soon as the question appeared Very good very good very good Each question is supplied with one minute forty seconds. That is hundred seconds Take time relax and respond read it. Don't make a mistake Again a similar agenda is being asked. Okay good good good good good good good good good good good good and good and good and good and Very good. I guess two or more people have to are 69 very good 70 No 68 70 very good very good good good good good Remember that when you responded. Okay, so everyone has voted so by default the system will conclude the question Yeah, and I guess I Skipped the right answer for everyone. I'll tell Charlie was the right answer. I might try Very good and responded very well Okay, any explanations required, please drop in a Y or M X for explanation required Very good sign very good Rashita. Sorry very good definitely very good very good very good So now look here relaxed and look if you still remember the graph it was I hear the current Voltage here. There was a shape like this here somewhere. It was C here It was somewhere D here. It was B and on that now you need negative resistance. That mean the slope Should be negative yeah, that mean this angle made with the eye current axis Okay, so should be obtuse And that is only possible in the case of C to D Yeah, beyond that it is acute before that it is accurate yeah So three considered Qtube questions. I have kept on the understanding of V by I All the three questions which we have asked till now were over the understanding of V by I is equal to R Ohm's law simple nothing else just a minor understanding of two-dimensional coordinate geometry Which you had in your ninth grade mathematics, which you are going through in your 10th grade mathematics as well Yeah, okay to proceed good Good good, but yeah, that's what is the collaboration of subjects. Okay, yeah, you have some related information you have a problem in Implying and utilizing the relevant and available and a known information you try to solve That's it You might not have ever thought about combining two-dimensional geometry with electricity, but yes here is the application and I know in classes There are our mentors The chaser is there. He always tell you the relatability between multiple concepts Okay, at times whatever I know I even I try to do it whatever other team members of us know they try to know it simply Please keep on trying to remember those please keep on trying to have a wider view toward problems Okay, let's trigger up the next question and first read this course by now Good. So Aiden. I guess is still leading the game very good. Yes. There is some shuffling happened in the lower Okay, bandwidth no problem. Here goes the fourth question. Stay calm. Look here concentrate read Think calculate respond quickly now very good Someone answered at the third or fourth seven second. I guess very good Very good Very good from next to ocean. I will myself alter the speed of the question Okay, someone want to speak something please speak up here. No problem 49 touch by almost Very good. And now by 50% of the time we have already crossed 57 58 very good. Very good. Very good. Nice speed. Nice speed guys Hope you are calculating thinking and responding. Okay, so and yes, the time in which you are responding is very clear Notification of that. Yes, you are solving it and then responding very good. Very good. Very good 67 is what we have touched by now 70 was the last score of last time 70 71. I guess I remember 69 we have reached 60 70 70 70 70 70 70 15 Simple application of R is equals to row L by a for last five second Simple application of variation of area with respect to resist radius. Sorry, not resistance Guys, you made a mistake Those who made six correct Clap for everyone, but those who have given an extra thought Okay fine And I'll tell you how they have done that They thought he very radius is varying from one to two That mean area will vary from one to four times Yes, sir. Yeah, sure Hence length should vary from one to four times So from five it should go to 20 That is what is the simple Method of thinking Shot I hope that everyone received it Those who have not kindly drop in an X Still dropping an X X X X Now why now why now X still an X Anisha? No problem dear. I'll explain that to you Good good good good good good X X X good good good good very good very good very good very good very good Very good relax Okay, now I'll Make you fall into the intricacies of the question Okay, and then we'll Here is the question Okay, simple visible I guess now check this a wire of length 5 r1 is row 5 by Pi 1 square Has a resistance of 1 ohm which is actually given as 1 What length of wire of the same material at the same temperature and of radius 2 millimeter will be used? Okay to have the same resistance so row 5 Pi r square should be equal to same material length required by R square again Yeah, so this is 4 pi pi row row L required is equal to 5 into 4 suppose you have one packet having four chocolate balls in that If someone will give you five such packets, how many chocolate balls will you have a 20 right? So fine Okay, so don't mind that Just drinking the monotony Hope is it clear now quickly drop in and I Yeah, yeah very good very good very good very good very good very good very good some long message was there in between I will repeat and then no problem there. I will repeat See see there Now this side LHS equal to RHS, okay? so now R1 is equals to R2 both one, okay? R1 is row L by a area of cross section I'm ignoring the units R2 is equals to row L required by a pi Right show now. Yes or no? Simple easy easy easy easy easy easy easy easy Okay Got very good very good very good very good excellent champions and here is our our scores for this question Here is the leaderboard for this question. Let's see. Oh Nice Good jump up. Eden. Don't sleep down Nana. Congratulations. Good job Others are kind of at the similar position. There is a simple shuffle between Eden Between Nana and the group Nana jumped a good leap and here goes the next question one and four and nothing Remember the dimensions because they will be required in the next question also So please keep them noted 1 centimeter 1 centimeter 100 centimeter Very good 21 people have already multiplied something 10 to the power minus seven Guys, can you please teach us this quick calculation of mathematics at least me us is like pretty wide group 36 responses Lesser than the number of responses we received in the last question by 30 or like by half the time There is 50 seconds past very good very good 10 or 11 responses are lesser in count. Very good guys going well by now Adding a hint R is equal to row L by a is again used last time Monday we discussed dominantly about Circuits this time we are discussing dominantly about the conductivity features resistivity features and other parameters, okay, so 66 by now 15 time remaining Very good. Very good. Very good. Very good. Very good. 10 R is equals to row L by a by Row is 3 into 10 to the power minus 7. Sorry guys. I am Tending myself a bit of cheating and here are the correct responses beautiful beautiful beautiful Okay, now first thing to ask doubts X X X X X X very good. Very good. I am very good. Varsha very good. Himanshu very good ishani. Very good. That's very good Ashnesha, okay Relax relax Now we are here Okay, and here is the question here This time RHS. I hope I will not have to prove LHS is equals to RHS and One one and hundred centimeter are the respective unit if we have to calculate our we need row Which is very clearly given Into L by a what then the resistance between the opposite rectangular faces Area of rectangular face is 10 to the power minus 2 okay numerator numerator length of The wire having rectangular faces will be one centimeter simple simple simple Simple. Yeah, I'll draw a figurative representation here and come explain Here is my whiteboard Okay, one centimeter better length length length Ashnesha length length is one centimeter. No, so guys Someone who cannot even draw in 2d is attempting to draw a 3d This is hundred. This is one and this is also one right So so in this case our a is this our L is this Yeah What is being asked between the rectangular faces between Rectangular faces between the rectangular faces from rectangular phase one to rectangular phase two so Anurad Good Everyone yes or no Why aren't very good very good very especially those only those who respond was required an auxiliary explanation no no problem at all So also the questions the like the options in the question said oh meter So won't it anyways remain the same whatever the dimensions repeat So the options in the question said oh meter not ohm so ohm meter, which is the resistivity It always remains the same rate doesn't depend on the dimensions Okay, I Really didn't get to your question are in I guess it's the voice of our incident Surya Chalo proceed One and two and let's see this course Simple here is the next question of the positions Sorry, you will see the question here on your scheme That's why I asked you to remember the above question now there should be a exactly I know because most of you have already calculated the other way around and that's why the speed and responding is higher very good Very good very good Very good very good very good 64 by 50 percent of the time very good very good very good Almost everyone has answered with 30 seconds remaining I guess one or two responses are being waited guys similar calculation But a varied area of cross section and length will be utilized and you guys know what is the answer Here is the time up Please four three two one and here are the answers. I guess there is this should have a dominant correctness Why this happened here? You again messed up with the units Guys play safe with the units Play safe with the units There is a reason we ask are you okay relax? I'll solve it for everyone relax. No problem. I'll solve it for everyone Relax. I'll solve it for everyone. I'll solve it for everyone. I'll solve it for everyone Same options are convert to the respective question Right similar options Again, three into ten to the power nine three into ten to the power seven whatever again R is equals to a row L by a This time the L will be hundred that is one meter and A will be ten to the power minus four Ten to the power minus two into ten to the power minus two will jump up will make it three into ten to the power minus three Guys What it I was expecting a blast of correctness Literally I was expecting a blast of correctness No problem multiple items are available. Okay so fine and Here are the scores the shuffled up scores the shuffled up scores So I guess there is a shuffling Yes, good poor poor have has jumped up a good distance a good leap Nana still maintaining her position at the top. Namesh is still there and with this warmth of the competition I don't know but here is the next question One response received in five seconds the first response. I am thoroughly today Going to check the whole list of The behavior and response. I might share it in the parent group If it will not be very satisfying or it will be very very satisfying and Here goes the 50% of the time Okay, and You have a Bandwidth of 40 almost almost 40. Please touch 40. Please touch 40. Please touch 40 40 40 40. No, I Was expecting a funny touch. Yeah because this is a like Question and relax Always remember I keep on telling whenever you get a new type of situation in life. The first thing you have to do is relax Relax doesn't mean sleep. Okay, relax Relax good 60 answered 15 is the time remaining now 10 in the is the time remaining now Again R is equals to row L by a is used and I have applied a simple ninth grade a formula for this question very good Very good and very good. Let's first jump to look into X very good Pratik Shah very good Rn very good very good everyone very good The first thing that I we don't know is one step Okay, to know that you don't know is the first step toward knowing, okay? Again the same thing or is equals to row L by a in a ninth grade Area multiplied by length is equal to volume. Yes or no? Quickly drop a wire or an L L three nine is equals to row L square L is equals to 3 by square root row Don't feel sad. Just feel enlightened simple Duh Simply drop an E for easy or that they are very good Excellent at it there relax simply drop an E for easy and An X for repetition Aditya needs a repetition and I will surely be doing that Pratik Shah very good. I repeat R is equal to row L by a is what is known The question is looking for the length in terms of the option still you in terms of row The options are telling L in terms of row is required Okay Volume is given here. How will I manage volume? So ninth grade? I have understood and I know that yeah, if I multiply L and L Then denominator. I'm getting the volume volume is stated as three meter cube three cubic meters So three goes here with the three ohm resistor given three and three are nine is equals to row L square implies that L is equal to three by square root So mathematically it should be plus or minus three But we know that the length can not be negative. Hence just writing the positive part of it easy now A L beta a L is given as three meter cube Resistance is given as three ohm Here I have stated that what I am going to apply Everyone everyone everyone quickly drop in a wire and quickly one comprehensive paragraph just miss I miss that I'll just Read try to read that some long message was there. Oh, Anish. Sorry, but uh Just check your like if you are using on a touch sensitive screen like cell phone and all Dear it might happens like You have to keep a distance or the cursor if you are using a screen. Okay, I Have tested this personally and it has happened with myself as well when we move the cursor by mistake It just takes a touch. Okay, and that is received as the answer as there is no repetition like we have in learners Right or not you answer the option once and then you can read him that that's a flexibility in learners But as it's a live running presentation with a leaderboard and time limited scores Time bound scoring. That's why it doesn't allow Rn coming with an expertise. Okay, I ran help out and we are by now proceeding to our scoreboard Let's see. What is the shuffling in here and People who were at the top are maintaining their position. This beautiful fish Aditya is maintaining its position In the top five three five three five three and all good. Aditya. Yeah, consistency is prior actually and by this notion we go toward the next question and here we have doom To do do the KBC background oops, I corrected it voice and it happened. This is Three, this is two and this is two The fourth option is Delta the four home register is 0.25 mpm People answering by now. I don't know what they might have answered I'm writing the option Delta over here the four home resistor Okay, is having a current of 0.25 mpm 9222 38282 and four the current in the four home racer is 0.25 mpm is the last option for anyone who needs that You might receive your answer before that as well just a minor What we call it a misdirective hint Last 15 seconds 50 people have responded 10 and 9 and 8 and 7 and 6 and 5 and 4 You should have waited for me writing the options Hmm. I am going for X Good Good good good good good good good good good good good good good good good good good good good too many X By some dear friend of ours or a why am I investing my time in drawing the circuit here? Anyway four two two eight Two two eight Okay, three two and this is nine So pretty obvious four two two eight parallel eight four four two two eight Parallel eight four four three two nine Our equivalent is nine home Implies that the current being drawn from the battery is one Quickly drop in an X if you have doubt in this part else. I'm controlling What is that glitch on it with the? People can't see the option question or options Okay, one second Voice is breaking as well for me Yeah option D was missing, but I was sharing the screen earlier I was stating the option D over on the screen. I was telling which what is the option D? Right near me. Yeah, I did stated option D on screen No problem dear Surya relax the final outcome is a learning just in order to garnish it We are doing it in the quiz shape just to maintain your end level. That's it. That's the harsh truth, you know Right Relax Proceeding our equivalent is calculated. It's one So one ampere coming here the first answer is in In a three-ohm resistor, there is one ampere current, you know There were two options relevant with three one was 0.5 and one was 0.25 so both are wrong now We are jumping toward four four-ohm register. There are two options. Sorry relevant with four ohm 0.5 and 0.25 right? No problem Suryani. I'll repeat Yeah, this is the setup. I have recreated the same setup here Okay so Now relax relax relax relax relax now the equivalent resistance four two two eight eight and eight parallel four four two two eight eight and eight parallel four four three seven two nine nine is the equivalent resistance. Yes, I V by R will be one ampere Okay, now the current being drawn from the batteries one will go reach over here I don't know at this very junction At this very junction, it will get equally divided why because outcome of this whole was eight remember Yes, eight and eight became four. So zero point five years zero point five years Similarly, we'll reach over this junction Half of zero point five here that is point two five and point two five So what will go through four ohm is a point two five, which is delta correct Okay, if or easy Yes for some way we manage Excellent Aditya Very good relax relax relax relax. I'll do that again. No problem relax relax relax relax see Breaking the whole circuit into steps four to two series eight eight and eight parallel four four two two again eight eight and eight parallel four three four two nine Our equivalent is nine right Yes, or no drop in a yes for our equivalent Especially those who have dropped in an X guys relax Let those who dropped in an X because at times this wave comes off your wires some X get just dissolved in that Meghana very good. I'll repeat two four four series. Yes or no Meghana why or N? eight eight and eight are in parallel four yes or no To everyone for two four four two four two again in series, right or not? Meghana Meghana Meghana Eight and eight again in parallel answer is four yes y or m four three two nine and nine one Both these yes or no Okay, relax fine then the distribution of current then the distribution of current one Goes and reach to this junction Right if you remember last class. We have also done if you want to verify it by Mathematical thinking so you know that we did a current division rule to Sharthur all also explained that right Current in first branch is equals to total currents coming upon some of the individual resistances into the opposite now here eight and eight were parallel were So 16 and eight comes I by two so what will get distributed is 0.5 here and 0.5 in this branch Yes or no Meghana Why or N? Yeah, similarly further half of distribution because eight and eight were here as well, right? So half of point five is zero point two five So so so so so so everyone got it got it got it very excellent Now moving to our scoreboard and here are the scores Some shuffling happened at the base top three remaining the same and here goes the next question Quickly answer that please Okay, one second one second one second one second one second one second the whole wire Okay, is off 10 to the power minus six ohm resistor Per one meter for each one meter length the wire is having a resistance of 10 to the power minus six ohm please It is bent in the form of a circle of diameter two meter a wire of the same material is connected across the diameter Oops Charlie and Delta are missing Everyone mark Charlie Charlie. I'm giving you hope everyone mark Charlie. I remember 0.88 is the answer everyone mark Charlie Charlie Charlie Charlie Charlie Charlie Charlie I Had corrected it guys. Sorry. Really sorry for this. I had corrected it That's why I remember the answer as well and then again it converted in the resolution So I'll sort it out how this happened so that it should not happen again Thank you for the patience Everyone if we'll respond as aptly as possible. We will have good time to depart So nine ten eight seven six five four three two one and Charlie Don't guess Please Okay, now. I know we should Explain this question. Okay, yeah, so here I explain it here Simple the length of each one meter is ten to the power minus six home. Okay for each one meter Now when it is made into a Into a circle, okay of two meter diameter Yeah, so it will have a Resist radius of one meter The total length of the wire will be two pi r Yeah, so the total resistance will be Two pi into ten to the power minus six You know and you could see that there were two semi circles joined with a third one. Okay So sure sure sure sure Fine now One such One such Box will have a resistance of one such arm will have a resistance of pi into ten to the power minus six There were two in parallel so pi by two simple also in parallel was Another arm with two meter length why because of the length of the diameter Okay, so two meter will be equivalent to two into ten to the power minus six homes So total resistance will be R1 into R2 whole divided by R1 plus R2 Okay, R1 into R2 is equal to Two into ten to the power minus six into pi by two into ten to the power minus six Hold divided by R1 plus R2 is equal to two plus Pi by two whole common ten to the power minus six This is ten to the power minus six what cancelled to and to what cancelled so Denominator is four plus five numerator is two pi Yeah, so into ten to the power minus six if you'll solve this Okay, you will get zero point eight eight. We solve and please solve and check Okay, so fine first of all looking for an x x x x mega x x x Very good are in very good very good very good relax relax relax relax relax relax relax relax fine This was the last or second last I guess I Repeat the question is every one meter length is equivalent to ten to the power minus six home You make a circle of Diameter two meter That means you are making one semi circle of Pi our Length so ten to the power minus six will get multiplied as own Any doubt in this those who are dropping an X? any doubt in this No doubt though, especially those without those who are dropping an X R relax Not everyone Okay, I Want to hear to those who have Issue solving it right or not so we are here to help them up and now this is also better same Combination of parallel for two equal reasons will be r by two so answer for the dots will be Pi by two into ten to power minus six any doubt and there is a diameter connected so two into ten to the power minus six for the parallel combination of two into ten to the power minus six as R1 and Pi by two into ten to the power minus six as R2 you will be able to calculate and get the answer Okay. Okay. Okay. Okay. Okay. Okay. Okay. Okay Very good. Very good. Very good. Very good. Let's look into this force Who jumped in? someone jumping The top three remaining the same next question. This is complete question. No problem Don't know how those two things happen, but I'm really sorry for that monotonicity Okay, it really broke broke the continuity of the flow continuity and flow of the lecture. Sorry for that Sorry for that continue answer eight answers received in last 20 seconds Relax, you should be able to answer this relax and then answer 60 third sorry 60 20 and 10 Continue continue continue very good. Very good. Very good. Very good 30 people have answered 35 V is equals to IR And in parallel voltage remain the same as the application of this question After 50 seconds, I give some hints. Okay. So So those who are guessing please if you will wait for 50 second Solve it and then also you don't get it At least you will get the correct answer by your own authentic calculations. I am guessing I am myself guessing that no one is guessing See speaking like Nikta Nandu Okay one eight seven six five four three two one zero Good. Good. Good. Good. Why please? Under the sign why for what? Nitiran Very good x very good very good very good very good very good very good very good very good very good very good very good very good very good Now again explaining you the stuff. I guess I can get that question at least This is another question. This is the previous one See see guys. I corrected that question. Then also it did not come So there is no way Here is the question we just now did Okay So relax simple The total current being drawn is one So the total voltage being supplied is i into r Let's calculate r first 1 by 60 plus 1 by 20 plus 1 by 10 Quickly 60 being the LCM 1 3 6 1 by 6 implies that 6 ohm is the r equivalent no doubt So good Now 6 volt is being applied by i into r So when 6 volt get applied across this terminal It will have a current i is equal to V by r 1 by 10 easy Got it got it got it got it got it got it I don't want to hear about him Got it any x any x please Especially x x x x x x x x x x x x x exactly Yeah, so I guess uh The experience of you with the physics is getting worse and worse right or not something happened in the Come on something happened today. You guys are really not responding properly. Give yourself some time Aditya have not even responded I guess. He has as he know This fish dropped into fifth position and we have Nana leading the game last question Quickly respond quickly 4 5 it's a question of less than 10 seconds actually you have to calculate only one thing which you know that's it 20 seconds are over Good. Good. Good. Good. 30 people have responded in just 50 seconds, which is very beautiful Not even 50 seconds 25 seconds Wow By 50 we will touch 40 Are we going to do that? Yes. Yes and Yes. Yes. Very good. Very good. Very good. Very good Relax and do that You guys will be thinking in mind you are yelling into our ears and you think we should get relaxed We are hungry at 9 30 and this man is pulling us long. Sorry for that deal But I have some very valid reason to do that Really, okay Please proceed proceed proceed proceed 21 20 19 18 17 16 V is equals to IR think about joining the S It will be easier for you if you will join this and one God good very good. Very good. Very good X please Okay, it's easier without joining as well totally yours X please very good. Very good. Very good. Very good. Very good. Very good. Very good. Very good. So here is the picture Right, but yeah, suppose this is open. So the current will flow like this, right? Our equivalent is equals to five Voltage was 20 so current will be four Suppose you might have been confused with another four here then join these Output will be one three and one four Voltage is 20 current is five. Yes. Yes. Yes or no quickly Everyone X please X please X please X please Very good. Make very good. Very good. Very good. Very good. Very good. Very good So looking at our stress, I guess Nana did not answer did she at last this Namesh, I guess he won the match. Let's see last question I'm sorry proceed This is tricky. Yeah, I remembered this This is the first this is inspired from the first question of last meet of us last Monday. We met Okay, this was the first question over there with some varied this Digits and numbers. Okay 18 people responded very good. Very good. 19 people responded very good. Take your time relax and respond Take your time relax and respond Good. Good. Good. Good. Good. Now. This is a good one Very good. Very good 25 remaining Very good A steady wave shows that people are solving it out, which is Positive for me very good 10 9 5 3 2 1 Let's see X please Mistake Anushka No problem dear Too many excess very good. Very good. Very good. Very good. Excellent Aditya Good. Good. Good. Good. Relax Let's take the pick first Of the question Right fine Relax, you are able to read everything. Okay. There's no number here. Simple The resistance of the voltmeter is 1000 ohms. So let's first calculate our Equivalent our equivalent will be parallel and then series parallel 1000 into 500 will be 1500 By 1500 R1 R2 upon R1 plus R3 and 1000 by 3 Is of what of this box plus 500 So 25 00 by 3 is R equivalent number one No doubt no doubt no doubt Yeah So This implies that the current Coming out is Current coming out is equals to V by R 10 by R 25 00 into 3 that mean Voltage drop across Okay So Voltage drop across 500 will be equal to voltage across 500 only Will be equal to why you know that why I'm doing this here I'll have to calculate much more here. I'll be very simple I into R 10 into 3 by 2 5 double 0 into R Oh, sorry. I have directly wrote the answer 6 10 minus 6 is equals to 4 is the voltage drop at this parallel combination 4 volt Being the answer Yes electrifying response Yeah, why why why especially those who have asked for an s Doesn't voltmeter Hey, relax. All right, sir. I'm extremely sorry. I have answered many questions wrong next time. I promise Relax. We are relax See in everyone's life there exists a limited number of mistakes So whenever you make mistake in a practice session be happy Because you are cutting short your coat of mistakes in life So when you make a mistake in practice ground, you will not be making a mistake at the real front. Remember that Okay, doesn't voltmeter tell only the voltage if I if think is parallel with it Ha, so that's what voltmeter is applied across the 500 connected wall This where it is Where it is where it is where is the beautiful combination here? So voltmeter is reading the voltage across this one Whatever be the voltage across voltmeter will be because of 500 and that will be because of the distribution simple Right voltmeter is not connected with the battery else. It would have noted the voltage 10 volts And it would know unwanted distractions. Thank you Okay guys, so Let's you not be blessed by another question And finally who is winning where did this oh wow nana Clap for this girl very good very good very good Very good very good very good You can easily see second position by namesh adan Very good very good very good very good very good very good very good Sure guys Congratulations. Congratulations. Congratulations. So sure, sir. If you are there you want to address them with something Or should I proceed with closing the lecture? five four Okay, guys. No problem. Sure. Let's close up. Thank you very much. Have a good night Stay safe Be there. I'll be soon. I'll try to be asap in bangalore. I'm missing it. Thank you very much. Bye. Good night. Bye. Good night. Bye. Good night
