 and started recording. Very good. Thank you very much. Who was it? Nice. So today at least we started at a very good time. At 3 we are starting at 8. By 8. By 5 I guess we will be very much in flow with this. Right? 2, 4, 0, 9, 1, 7 is the code. 2, 4, 0, 9, 1, 7 is the code. Very good. 43 people. Very good. 53, 52. Good, good, good, good, good, 57. 60 will touch. We will start. Whichever it will touch first. 805 or 60. We will start. 60. 1, 2, 3, 4, 5, 6. Usually you have 70. Let's see. Let's see. But today is like the first day for the close down thingy for you, right? Your lectures and all that. Out of yours, vacation. This is the first day that there might be a reduction of 10 odd people. No problem. We can still wait for 8 to 5 and accordingly can start. Okay? Yes. Most of the question which will come, which will appear on screen will be based on power. So here it's 805 and here it's 61, 2 and go. What a good speed. What a good speed. What a good speed. Good, good, good, good, good. What is it in kilometer per hour? What is the question? Okay. Speed of answers per second. I guess we will have to count for answers. Everyone has voted very good, very good, very good. And here we go with the correct attempts. Okay guys. So we know that for very obvious reasons neutrons cannot be disturbed. Protons cannot be disturbed. Okay. So electron can be either removed or can be given. When you give the electron, it brings negative charge on the body which receives the electron. Clear or not? Sure. Okay. So giving excess of electron to it will make the body negatively charged. Clear? No problem. Here we go. First with the leaderboard shot. Let's see what's the difference between the top 5 people and the beauty. Wow. Wow, wow, wow. Very good, very good, very good. The beauty is like very minor difference. Okay. So no problem. Any random name, anyone who I know like Tushar. Aden is here. Vibhav is here. Aniket Gupta is here. Aniket Mongara is also here I guess. Good. Sneha is also here. Very good, very good, very good. And here we go. Next question. Look, read, solve, respond. Guys, you know this calculation. Okay. Clear? And I have also told everyone in general as well that this is the favorite question of NTSC. This is most favorite question of NTSC. This is most favorite question of NTSC. Simple calculation. Don't panic. Just, just, just know like very random or very rare conversion is also there. There's nothing like that. It's a very general conversion. You know all of them. Okay. Not even by calculation just by at your fingertips. You have to just put and multiply. Okay. For the very last few left, I'll just state everyone has voted very good, very good, very good. Let's see. Let's see. 100% correct. Boom. How come? I can see some people are saying sorry and all that. 1 kilowatt or 1 kilowatt 36 into 10 to the power 5. Rocket science kilo is 10 to the power 3. R to second is 3600. Anyone want to drop an X again? Okay. Good. Thank you very much. And here we go with the next question. And before that, giving a look to the leaderboard. The fastest responder was Aniket Gupta and Aiden Thomas like oh, and a slasher as well. Excellent. I've never seen it before. Very good. Very good. Very good. Very good. Very good. Like wow. Excellent. Excellent. Excellent. Very good. And here we go with the next one. Maintain the same pace. Yeah, this will take a bit while in order to read it. But no problem. Good. Good. Good. Pretty honest while responding is like beautiful. Looking at honest people when the answer is beautiful, beautiful, beautiful. Mongara left the audio session. I guess he might be just concentrating over the quiz. Preparing for it. Yeah. You just left the audio version. You are here with the chat. Good. Guys, you have to read it. Surely the reading will take some time. But yes, the concept is very simple. You know the formula associated with power. Okay. There are three versions of them. Apply them. Get the answer. You will have to think about what is constant and what is varying. That will help you out in order to get that answer. Yeah. So first of all, two electric bulb both are having same voltage. This voltage comma power is called as rated. Yes or no ratings. Power ratings. Okay. So both are working over 200, but one is having a power of 40 watt, whereas another one has a rated power of 100. Now when voltages are same, which formula of power will you use when you have been provided with exactly, exactly, exactly v square by R, which tells you that R will be higher for lesser power because R and P are inversely proportional. Correct. Correct. Correct. Correct. Correct. And hence the resistance of the filament of 40 watt bulb is more than the resistance of 100 watt bulb. Okay. So lesser power will have a will deliver a will provide a higher resistance. Guys, please, please, please, please, please look here. Let's see the shuffle in the leaderboard if there is any. Ah, here there is a difference built up a difference built up here. A bit linear, but good. Aiden jumped up to a good position. Gupta, I guess you made it wrong. Or you took time in order to solve it. Where is my dear friend, Ashleisha? Okay. She might be somewhere down and all that. Good. Good. Good. Good. But only one fastest. Okay. One, two and next known question, known question, known question, known question. If you have appeared yourself in the Camon, this is a known question. Camon, known Camon, known. You know it from Camon. If not, then yes from our discussions. So understand that the position they tell you is like your fourth and all that. That's the position of that particular question. Whereas what appears on the leaderboard is cumulative position. So you might see a variation. Got it. Chalo. Anyway, concentrating over here. Why is fuse, fuse wire use is pretty valid point to discuss over here because the responses in the answers are like the material of a fuse wire should have. Now why a fuse wire is used for what this fuse wire is connected in the circuit. For what this fuse wire is connected in the circuit. So your answer anyone to prevent overheating or to prevent excessive supply of current. What happens whenever an excess current comes because of I square R this heats up melts down in order to melt down early. It should have a low melting point. Low melting point, low melting. In order to allow a good passage of electric current should have a low resistance. So it should have no specific resistance because specific resistance and resistance are directly proportional to each other. Hence Bravo will be the right answer. Aditya what happened? Aditya G. Where is the doubt here? I just want to understand that part. You can unmute and speak up. Low resistance. It should have a low resistance. If see suppose simply understand that this wire is there. If it will have a high resistance how come current will come to this? Current passes maximum from the least resistance. We need this here to allow easy flow of current very well stated by shares. Good. Thank you very much. Also understand the fuse should not act as a load for the voltage supply. Here is our leader board. Good shuffle happened. Switch a swap. Gupta tending to lead the game again. Only one fastest. No problem. And here you go with the next question. Read it. Invest your time. It's confusing. You might think one is to two but the answer can be two is to one. All the calculation etc might be correct as well. Just see the right sequence. What is required? Two is to one or one is to two or the other way. One is to four or four is to one. 54 people responded in half of the time is pretty good. But this question actually should be done in odd 30 to 40 seconds. But in that case the possibility of you making a character is only 25% whereas the possibility of you making wrong is 75%. Don't go for guess. Boom. Again. Back. Look to the question. Read. Heater coil is cut into two. Hence the resistance will become. Old resistance is R. New resistance is R by two. It is being supplied with the same right or not. So the ratio of the heat produced by half coil to that by the original coil. So it is being operated at the same supply means voltages are same. So old performance was this. New performance is V square by R. The ratio of heat produced by this half to by old by one. Two is to one. Alpha being the correct answer. Everyone okay? By one end quickly. No one want to drop an X. I am waiting for X specially. Good. Good. Good. Good. Good. Good. There was some X. There was an X in between. Okay Aditya very good. Very good. Very good. Very good. Very good. Saw it. Yeah. Yeah. I read it. Very good. He didn't thank you very much for helping me. Aditya thank you very much for recenting. Now Aditya. There is an idea. All the time the power being delivered was V square by R. Better now. See in domestic utility you don't use series. You use parallel. So how can current be same and current will be same to what? Current will be same to what? You don't supply current to a device right? You supply voltage to a device depending on its resistance it absorbs current. So current is not a variable to be taken in there. Okay. What is the variable to be taken in there or voltage and resistances? Okay. So all time V square by R by application of a voltage V because of the presence of the resistance R. Okay. Okay. So if you want to go by I square RT I will go by that method also. I will go relax. I will go by that method as well. Don't worry. If you want that comprehensive answer I will go by that method as well. And I will show you that this wrong. Okay. I will tell you that relax. So heater coil is cut into two parts equal length. The ratio of the heat produced by this half coil to that by the original coil. So original coil was delivering V square by R. Case one. Okay. Especially those who have only those who have dropped in an X. Okay. Now case two the same voltage will not the domestic supply will not change its voltage. The voltage will remain the same. So V square by R is R by two this two jumps up taking the ratio two is two one method number one. Now method number two talking about our dear friend's answer as I square R. So anyway new by old. Okay. I new square R new square T square I old square R old square. Why I am taking T as T square. Boom. Boom. Okay. T. Now simple. Cancel. Right. So I new square by I old square is not known. But what is known is R new square R old by two square. So for R square R old square R square. Cancel. Okay. So clear. Oops oops oops oops I square R T. Sorry. Sorry sorry sorry sorry sorry. Okay. So R new R old one by two. Now what is the value of new current and new old current. So if old current was I new current will be V is equals to I R with the resistance of R. Old current was I with the resistance of half of R new current will be two I. So two square this will be four cancelling two is two one. Satisfied. Satisfied mega. Okay. Very good. Very good. Very good. Very good. Then really speaking doesn't more resistance mean more heat depending on which type of circuit you are there. Okay. So later board again have Surya from NPSYPR responding fastest. Very good. Good. Good. Good. Good kind of consisted in the second third position and all that. There are few known names disappear and here you go with the next question. Now now now guy this is a similar question plotted on the same concept. Slight variation please apply and get the answer. You have done so good so far are. Ah. 60 people have already responded in a time less than half the duration. good good good good good and 30 last seconds please reject we will be really happy to see that everyone has voted and yes everyone has really voted very good but someone again came in okay no problem no problem no problem just relax think about the cases think about the possibilities and here we go with the scores actually looking at who and how many have done it right and all that why 30 again you went with voltage now here it was clearly stated that the arrangement is of series so I square R will be applied series connection I square R will be applied okay and hence I square R I square R 1 is to 2 okay whereas we say beta in series circuit voltage doesn't remain same it gets distributed please please please don't it's painful okay next let's see the leaderboard first who has responded the fastest which is very high agenda and then we will see the top scorer Aniket Gupta not scoring anything Samrud is the fastest one to respond Surya and I indicate maintaining their top positions but having a good hustle in between themselves and here we go with the next question as of now we are running really fine we are really running fine because the upcoming questions will take a bit longer a bit comparatively a bit longer so we are at 8 30 another six odd questions are there so you guys will be happy to have this concluded on time today so again a similar thing but yes there is a variation in resistance and resistance variation can be easily calculated by arranging them in series or parallel as the question directs that variation will influence your power outcome hence the multiplication will give you the answer direct explanation I have given you now please please please quickly finish this equal word is very important over here equal word is very important over here and the beauty of these things are these are all NTSC's favorite questions these are all NTSC's favorite very very favorite questions it's okay Surya we should save time you can see on your screen out of how many questions which one you are seeing seeing right okay okay okay and sad look here three equal registers corrected in series 3R power outcome will be equal to V square by 3R right so power outcome is equals to 10 so V square by 3R is equal to 10 right if the same registers are connected in parallel R will become R by 3 so if it is V square by R it will give me 30 right or not so if it has to be stated 3 that's multiplied so it will be 3 multiplied it will deliver me 90 everyone everyone everyone quickly quickly drop in an X very good area you have a doubt I'm considering that very good area very good very good Sharon very good very good very good very good very good very good very good very good very good across the same emf didn't you read this please so old power is 10 which is equal to V square by three equal registers connected in series 3R new power required is V square by R by 3 why R by 3 why R by 3 because now they are same registers are collected in parallel so you know their equivalent resistance will become R by 3 right take the ratio 10 by P equal to V square by R V square by R cancelled 1 by 9 P equal to 90 okay okay okay especially those who were experiencing an X very good very good very good very good very good very good very good very good very good and here we go with the leaderboard first and then we look for the for the for the for the next question and Aniket scoring some good points might jump oh wow Surya you just got saved okay Aniket responded it fastest very good now going on to the next question read the questions you will have your answer within there a kid's question you should just know multiplication that's your answer yeah exactly eight and six point difference Surya got saved else he might have lost his position he is just a multiplication question Ray just multiply and you should know what is kilo yeah you got this one wrong upta happy be happy Surya will be like boo-hoo guy 61 is good score by like half that time it's good yes I have given a bit wider span of time to solve it because I wanted you guys to make it more as a correct vertical I did not I never want to compensate your accuracy with your speed at least at this age okay so so here we go at the end of the duration of discussion for three two and one everyone selects everything 15 only 15 hour look here how much energy energy is consumed kilowatt hour you have been provided with what okay you have been provided with our right or not so this is what are available per day for 30 days these many what ours so 1 2 3 makes it kilowatt hours 5 3s are 15 okay wire and wire and shame on me I'll oh damn I have to skip today's dinner so one second let me see which question is which option is right first oh sad sad about 19 people 10 such bulls are there so it will be oh why did not they write it as 1 0 yeah this 10 got hidden punishment no skipping dinner and all who got lucky let's see a Gupta got lucky he has it wrong Surya got lucky and but Surya got a bit unlucky with a difference of odd right or not 70 point and all no problem here is your next question don't worry don't worry don't worry don't worry and here we go similar question you have already done it please please please please please by asking which one will grow brighter they are indirectly asking higher power I'm just telling you about asking about this they are indirectly asking about power please please please huh it's okay not the time is also up right I should give answer I'm here to give answers only right or else you don't need me we'll make anyone sit over here and they will just click keep on clicking arrows everyone has voted very good very beautiful 67 and 543 to boom let's see let's see let's see oh oh ho ho ho let me see first whether I am right or not so 25 watt bulb okay 100 watt connected in series series series which electric bulb will glow brightly it will be 25 watt exactly higher r will deliver a higher power in series arrangement now higher r will be delivered by a lower p that means lower p will glow brighter in a series element got it anyone needs an explanation drop in an x very good very good very good very good very good very good very good very good very good now I'll tell you what see here you will have to first calculate their design the resistance their design resistance are v square by p and similarly from here for very obvious reason this is r25 and this is r100 you know r25 is way big than our hundred right all right four times right now power is directly proportional to or in this case because the case of series so our higher implies that power will be higher implies that glow will be brighter okay so 25 clear clear clear clear clear let's see let's see let's let's see let's see mega something happened Meghana once again ok here we go see we need the resistance of this device right so resistance is V square by P suppose this is V both are same I am just writing V square by 25 and V square by 100 so this is our lesser value of denominator means total in total higher value so now I square R I square R are the power outputs right I square and I square are not important reason being they are in series I remain same ok now R of 24 and R of 100 you can see very clearly R of 24 is four times R of 100 and this is bigger that means the power output will be bigger got it got it got it got it got it very good very good very good next question first of all are good shuffle shuffle shuffle shuffle shuffle good good good very good very good very good here we go with the next one, moves quickly relax there is a good possibility of making mistakes so please don't do that there is a good possibility of making mistakes so please don't do that read carefully whether it is series or parallel that will be helping you out hmm I shouldn't have given this long time for this question but not at all a problem not at all a problem good good good good good good quickly relax huh the best thing is you guys are solving it out that your response frequency and that the tsunami which comes as the response it's come is it's coming into installments good good good good good good good good good let's see 10 9 8 7 6 5 4 3 2 1 boom oh still still still still still two bulbs are connected in parallel and they together consume 48 water yes or no so no doubt no understand v square by R is the power in first and v square by R is the power in second yes or no no doubt fine okay in total they are consuming 48 here from a battery of 6 watt so total voltage upon total resistance is equal to simple simple simple simple simple simple 48 v square by R is equals to 48 so R is equals to 36 by 48 which is 3 by 4 now this R equivalent is R by 2 why because parallel combination the resistance of each bulb this line indicates that they are equal because in the options there are only one things available right or not R by 2 is equals to 3 by 4 implies that R is equals to 3 by 2 1.5 okay okay okay okay okay okay okay anyone want to drop an X very good very good very good very good very good very good very good very good very good quickly leaderboard might have got shuffled yes there is a possibility of Surya where are you now huge 1000 point difference yeah other downward shufflings are continuously here where is Aidan Thomas disappear okay relax look at it and solve if you know the formula you have the answer in front of you if you know the formula the answer is in front of you if you know the formula the answer is in front of you calorie are calories guys this is just looking at and giving the answer look at it and give the answer there is only one family a term others are all Ulu banana just making fool of you it's just a question of lesser than common sense thing if you know the formula you have the smile only by one gate that's already represented here right please guys five four three two one great good to see that but still please please please please please okay I square RT is the formula nothing else was there for the brain and here we go with the leaderboard so Gupta is leading there's a huge 1000 point gap now between the top two ranks rest others are there a good shuffling is possible in the last question I guess look at it and respond quickly quickly quickly quickly relax and respond relax and respond you have been through this thing several times throughout this testing size you have been through this several several times throughout the exercise so please read that and respond and solve finish this question before the time actually ends simple right simple very simple very simple you have been doing and dealing with this right good good good good good good good good very good very good very good very good very good very good yeah guys quickly same thing 25 40 and 60 are what what is the unit of power power have some relevance with resistance we have been discussing about it from almost question number two I guess quickly are 10 and 9 and 8 and 7 and 6 and 5 and 4 and 3 and 2 1 good but still there is a requirement so 11 was no brainer I square RT right now 12th one guys again the same thing power and resistances are inversely proportional to each other when as soon as the designing is considered right and hence 25 watt will have a lower resistance now suppose this question would have been asked to me okay sure not from the perspective of a 10th grader then I might have responded to okay information is insufficient why because r is equal to v square by P so their rated voltage can be different if they rated voltage would have been different they will deliver an equal right or not at the variant like non-symmetric patterns of R okay but anyway for this case R and PR inversely proportional the lowest P will give the highest R which of them has lowest resistance lowest resistance will be offered by 60 watt did I did I mark did I mark did I mark alpha beta Charlie or Delta are correct correct 60 watt on a lowest will be responded by 60 highest will be responded by 25 I was correct explanation I just was confused whether I gave you AS correct or BS CS correct and here you go with your leaderboard is there a shuffle is there a shuffle Shurya attempted but missed by some 200 points 100 points okay so clap for this chap and he gets Gupta has been attempting it for for God knows how many days and finally making it up at the leaderboard good good good good good good good good good very good very good very good very good very good very good okay guys okay okay okay okay okay okay relax relax relax relax so this was my attempt toward two things bringing into conceptual approach towards symptom are one let's making it a mix of numericals and concept one second yes trying to attempt or keep as many questions and that type of question that this can actually become an hour instead of becoming a one and a half hour show it should become a one hour show okay we are like short of two questions I guess if I would bring instead of 12 15 set then that might okay thank you very much for your time very good very good nice being here utilize these time which you have been provided for like out of the classes and all that your classes won't be there so take care good night bye bye
