 So shall we start? I think Anand and you said you have to wait so we can start and let's see. Okay, so let's begin guys. Here is the first question of the evening. Let's see how many of you can get started. This is first question compound. So I think you will answer quickly. All of all would be voting quickly. Easy huh? Everyone knows it. Okay, I think most of you have got it. Absolutely yes. Florian is the answer. Oh amazing. So lots of people know this. So you are really generally aware. Okay. First leaderboard. First Janvi. Cool. Devil Rishabh NPS INR. Okay. Cool. Very good guys. Let's go to the next question. Okay. Here is the next question. Sorry. Whereas if you can play on a laptop that fast, it's also easy. Yes. Now why? It is very common. These are all, you know, things of your, what do you say, daily use. You must be aware about all of that. Oh, that's so poor response. So you don't, Mylon is the answer guys. It's made up of Mylon threads. Okay. So that means your general awareness level goes down from here. This is the leaderboard. Ahaan. Okay. Cool. Lots of people from top 10. That's nice. This, these type of quiz will see lots of shuffling. Very good. Cool. Let's go to the next question. Kyle benzene sulfonates. Where do you find them? It's there on the screen. My screen. Look at my screen and answer. I'll Kyle sulfonate. I'll go benzene sulfonates. Where would you find them? Yes. Very common product. Oh, most of you have got it correct. So did you really know this or how many guests? How many got it correct? You do guess. How many knew it? Can't even pronounce it. It's called alkyl benzene sulfonates. Okay. So remember this the common ingredient in detergents that you use for washing your clothes. Alkyl benzene sulfonates. So it's a organic compound with sulfur. Sulfur, I think. So, yeah. Next. Oh, this is a leaderboard. Oh, lots of shuffling. Cool. Duma is now on top. Nice. Next. So you have seen this, right? Quads. Why do we write quads? Why is quads written easy? I think knows it. So those who know, it will be easier. Don't know. Okay. So it's because, you know, yes. So 16. Very good. See, basically quads is a piezoelectric, I don't know if you know, piezoelectric material. So when you pressurize it produces electricity. And when you give electricity, it starts oscillating. So there's a very fine tongue of, you know, tuning for kind of a thing in the quads. So there's a quads crystal is used to make up what is a tuning for kind of thing. So when you when electricity supplied to it, it starts vibrating. And it vibrates very precisely. So in one second, it vibrates those many number of times, which is, you know, calculated and time is kept using that. Okay. Okay. So guess what is going on? Oh, that's nice. Very good. So next, let's go to the next question. Now let me see how many of you can answer this. The maximum current which a typical household air conditioner can draw is. Oh, so fast. That's nice. Okay. Still many people have got it correct. So good. You get it. See, you have two types of electrical circuit in your household. Do you know this? One is 15 amp circuit, one is five amp circuit. Okay. So there are two different electrical circuits in your household. So the heavy equipment like geysers, yes, geysers and air conditioners, refrigerators and microwave ovens. All these are, all these use 15 amp circuit. The five amp circuit is for television, fan, bulb, lights, you know, yes, mixer grinder and all that. Good. What about 45? In our household, we don't have any connection which can draw 45. Forget about, you know, 15 is too much. Usual amp here is around 10, 11 amps, 12 amps maximum. 45 is way too high for a household. Cool. So number that is in rank one position, Dhruv, Prateek, Anuja, Nishant, Ronald, Ronald, Ronald is from where I don't know, Siddharth and Sathvik and Higu and Himanshu. Next. Okay. You have used, you have seen this a lot. You have seen this on a daily, you don't know. Time's up. Okay. So it's basically, you guys can't quote of calcium car. No. It's basically, you know, the, there are different colors of light which is produced inside. They blend, they mix together to give you a sensation of white light. Okay. So you'll understand. There's a very important, very interesting mechanism behind it. I'm not going to describe more because there are questions related to it later. Next. Okay. Okay. Okay. Okay. Very good. So Prateek is now on position number one. Next. Let's go. Which of the following elements would you find in a compact fluorescent lamp? It should be easy. Very dangerous element. Very dangerous element. It causes a disease called, can you name the disease which it causes excessive exposure to? So what is the, still people could not get it. Yep. So, yeah. So what is the name of the disease called Minamata disease? Do you know this Minamata? Minamata is a place in Japan. Minamata disease. So I don't know if you're aware that we have to phase out mercury usage. Yes. So we can't use mercury. And if so, hence you will see the lot very less mercury thermometers available these days in this thing. So yes, it creates a lot of arsenic is more deadly. Yes. But then arsenic is not commonly used, but mercury is very much in use. Right. So if you see the tube lights are gone now in tube lights earlier, they used to have mercury very, you know, interesting from and which happens inside. But exposure to mercury is dangerous because it leads to something called Minamata disease. So now the world has decided to phase the uses of mercury out fine for the, I will give you more clues. Next. Next question. Folks ready. Anuya is now in the first position. Lots of reshuffling is happening. That's interesting. So it's interesting to see. Okay. But the people have all CFL consumes power. How much power does it consume? So look carefully. What is the right answer? So you must if you have bought it ever, you must be knowing it. Easy. Right. Have you ever bought a CFL lamp? Yeah. Ordered or gone to electrical shop and bought it. So what do you say? You know, typically what is the range? So still many of you are correct. Good. Good that you didn't write this is, you know, there was a trap. Someone was asking what is the trap? This is KW kilo watt. So, right? So it is three to 15 watt. What is the unit of? What is the unit of? What is the unit of power? Okay, what is the unit of energy? Unit of energy. Joules. Okay. And then what is calorie? Calorie is unit of heat. And what is the heat? Heat is not energy, form of energy. Right? Okay. Good. Sensible heat is measured, you know, in joules. Anyways, let's go to and calories. Normally, calorie you have heard in what in your food products. And while going to a gym, you say all that. How many calories do I burn? Hmm. Next question is, oh, first of all, the leaderboard not doesn't show much of a difference this time around. Yeah. So almost the top 10 are still the same. You want, you can do it. But then 20 seconds, what will you do? And what will you find instead of that? Okay. Hello. Next. This is an interesting question. Let me see how many of you can crack this UV is ultraviolet. Okay. Mix. There is no filament. You know, so there's not it isn't in incandescent lamp. What was invented by Thomas Alva Edison. That is that lamp where there is a tungsten filament. Right. But here what happens is, yeah, there's mercury. And, you know, electrons fall on to them. So electrons, you know, come out of them, you know, the, you know, the material, the element over there goes to a higher energy level. And then sir clues, clues of what? Now the question is over. Right. And then what happens then the electrons come back to their, you know, you'll study this in chemistry later on. Electrons come back to their normal state. And while doing that, whatever energy they had gained a release in form of UV rays, UV rays, these rays then go and hit something called a phosphor material coated inside. Okay. Any more question on CFL? Okay. So it emits, you know, that phosphor material, then emits visible light or different color which gets mixed and you see it as white light. Okay. Next question. Maybe one more question on CFL. I don't know. Cool. No, Ronald is I come on guys, Ronald, Ronald is someone unknown person is on top. How can that be with you guys? Hello. Come on. Cell phone batteries. I don't know if you've ever observed. You remember on trains? Okay. Okay. Time's up. And here is. Okay. That's cool. That's cool. Many of you know it, but many of you don't know it. So must be aware. Okay. Fine. So, yeah. Okay. So now, you know, three to five volts, right? Typically 3.735. You can check it on the adapters. Okay. Okay. So, oh, no, yeah. Just, oh, anyways, you are way ahead. Good. Very good guys. Shallow. Next, let's go to the next question. Wearing in the household electrical circuits are made up of should be easy. The cooking word, Ahaan, courier it to me also a little bit. Okay. Very good. Oh, that's so nice. People are so aware. That's cool. That's nice. Here is the, oh my God, almost all of them were close. Very good. It's not aluminum. It's copper. Right. Let's go to the next question. Very good. Come on. Come on. Yeah, this one. Those who have not observed it properly. So if you've got it, nine volt battery is not double A. Okay. Wow. Cool. Nice. I'm really happy to see a lot of people know right answers. That's nice. Here is the leaderboard. Anuya is maintaining the lead. That's amazing, guys. Good. Very good. Come on. Come on. Come on. So who's leading Indranagar? Ronald. Who's Ronald? I didn't, I forgot. Ronald was with school. Abhishek. Okay. Indranagar. Okay, great. Abhishek is there. So Indranagar, Indranagar, R&R, R&R, R&R, I&R, I&R, R&R, R&R, R&R. Okay. There is no K&M and SSR. What happened to you folks? Are they not there maybe? Anyways, so next, next, go to next question. So let's see who wins Indranagar or R&R. Trophy goes to whom? Well, add the points of top 10. Let's see. Has to point in which of the following directions. Interesting. Let me see how many of you know it and have ever observed and you know the reason also that's important. You have DTH, antennas, right? Right on your rooftop. In which direction they point? All of them point towards only one direction. Have you seen that? No clue. Think. Okay, think. I want you to think. This is very common, sensical question. Why do they point towards, yes, anyone can unmute and say, I will be really happy if someone can explain this. Related to geography. Related to astronomy. Related to science. Anyone? Anyone? Those who got, those six, who all got correct? Is it guesswork? Jaanvi. So Jaanvi, do you know why it is pointing towards Pradeek? Do you know why it, why does it point towards south? Right? So I said, what is it pointing to? What is it pointing to? What is, what does it point to? The sky, satellite, right? What kind of, yes, yeah, some shit guesses a satellite. What kind of satellites? It's called geostationary satellite. Geostationary satellites, right? Geostationary satellites usually are, yes, I'm only thinking wrong, but I have to, yeah. So geostationary satellites are satellites which are always on the same position above the, in the sky, right? So hence, otherwise you have to keep on rotating the dish antenna. So right, and geostationary satellites mostly revolve above equator, and equator is in which direction of Bangalore. So hence, that's the, so you should observe and ask this question. Okay, so next. I don't mind, I can do that. If people are interested, but today only 30, I was disappointed. Many people should have joined him. Anyway, it's cool. So let's go to, yeah, around 26,000 kilometers, correct? Next. Yes, who's this? Sir, this is Raghav, I just joined. I didn't know there was a centermar today. Have we changed the schedule for centermar? Same, sir. This is Gandhar. Hey, how many times did I say in the last centermar? And in the classes also I told you, don't tell me. Did I not announce in the class also that on Sunday we are going to have a general event? What is the schedule for centermar now? Same thing, same thing. It is an extra centermar for you guys. I told in the class, but then we got a message. Leave it, leave it. Let's focus on playing. We'll discuss it later. Okay, good. TV remote uses which of the following communication infrared rays? I don't know if you have tried it. If you look in the opposite side of television, if you wear specs also, and if you point out the remote on your specs, it will, yeah, yes, it will still work, right? So you have to use it on Arduino. So Arduino also uses that remote control, uses infrared sensor, you know, raise communication, IR communication. Okay, okay, good. Okay, okay, okay, okay, okay, not much of a change. Anuya is still maintaining the lead. That's cool. Anuya is a, you know, quizder or something. She quiz, she participates in quiz. Yes, I use Arduino. I use Raspberry Pi as well. I used to do a lot of that in my earlier days now. Liquid and petroleum gas has which of the following gases as it's This is carbon. I really like it. So cute. Really, really cute. Very good. Yeah, it's like conbini acrobatic, right? Wow, propane and butane, right? So these are the basic hydrocarbons, which are used for, oh, which are used, which are mined and then, you know, learned this year, very good. So, no, see, I apply, you know, application, methane and hexane, not there, methanol, ethanol are alcohols. So, you know, but they are also combustible, you know this, but they are not part of LPG. Methanol, ethanol, both are very highly combustible. Ethene and benzene are not there in this. Okay, next. Cool. Okay. Okay. So still Indranagar, oh Indranagar are closing in. Good, good, good. Next. This, you know, you were discussing this. You were discussing this. Right? Why do we need to add ethyl mercaptan? You know this already, but why do you need to? Reason be, why can't the pure gases be there simply? Because the constituents are odorless gases, methane, ethane, propane, butane are all odorless gases. If they had some odor in themselves, you didn't need ethyl mercaptan, isn't it? Okay, fair enough. So, you know the formula of ethyl mercaptan, anyone? Anyone knows the formula of ethyl mercaptan? Yes. Tell me. What is ethyl mercaptan? Anyone? I think it's C2H5S. C2H5S. It's not CH4S. Yes. Right? Okay. Let's go to the next question. Good that you retain your previous knowledge. That's good. See, these are all general awareness. You must know these things in your household. Okay. Next question. Oh, before that. So, Anuya is well-maintaining her leads right on top. That's nice. Let's go to youth pencil Delhi. Ambatow. So, you know this? Oh, that's cool. People are generally aware. Very good. Question, guys. Oh, before that, the leaderboard. Okay. Yes. This is the, wow, so close. Really good. Really good. Really good. Cool. Cool. Come on. Come on. Come on. Faster. Above. Come on. Come on. Come on. Come on. Come on. Compound of which element would you find in a deodorant? You use. Very dangerous. Wrong answer by a lot of people. It's aluminium. So, now it is, you know, they are talking about, you know, there was some, I don't know, rumours or what that aluminium compounds create Alzheimer's disease or lead to. So, hence they were trying to. Yes. Right. Aluminium. So, lots of aluminium compounds are there, which are there in the deodorant, which they are trying to not use because there are some doubts that they might cause Alzheimer's. Okay. Next. Okay. Cool. Next. Come on. Come on. Come on, folks. Faster. This you must know. Where have you seen this? You eat lots of packaged food daily. You must know this. It's called Food Safety and Standards Authority of India. Thank you, Ashish. Okay. Understood. Good. So, you must know every packaged food must contain, you know, this label behind the, you know, or wherever somewhere in the food packet panel. Okay. Next. Use it, then you eat biscuits, chips and what not. Oh, Anika is now, oh, I don't know, people have taken over. Very good. What has happened? I don't know, people, come on. Next is your question. Where do you see this? Yes. That means you don't really, you know, look at the equipments and tools around you. It's your opinion standards, right? So, you know, if you go and purchase jewelry or, you know, anything where weights and measures are involved, there you will see this kind of logo, right? Okay. Very good. So, lots of people have guessed only Namrata and Dhruv. Okay. But not much of a difference in the leaderboard as such. Let's go to the next question, guys. Here is the next one. You have seen this capsule here. Well done. Well done. Where have you seen this? Tell me a place where I have seen this UPS. That's cool. Okay. Where else? Where else? God knows. Janvi says UPS is one. Where else? Movies. Inverter, yes. But in your five guards also it is there. Voltage stabilizers, very good. Normally, all the equipments have. In fact, your automobile, your vehicle also has this fuse. You didn't get a point, you didn't get points here. Okay. Electric fuse, right? But how can that be? Electric fuse, it was never mind. Let me see how many of you know this. These are very common in use. What are they made up of? Most of you know. What is this called PET, right? PET material, polyethylene. All are plastics for that matter, Nishant. Polystyrene, beccalite, polyester, polyethylene, terephthalene, everything is plastic here. Right? There are different forms, types of school, Janvi. Common sense, good. Good, good, good. But you now remember, what is this? Polyethylene terephthalate, okay? PET, you say, right? PET bottle. PET bottle, polyethylene. So, polyethylene is what? What do you know? What is called, you know, polyethylene? Polyethylene is, yes, PET, right? Polyethylene terephthalate. Now, polyethylene is the common, you know, plastic, the common parlance, what we use, common, you know, the polythene bag, what we call it. That's polyethylene. These are all polymers. You'll study about this in chemistry. Polymers. Hey, Hanika, still very good. Nice. That's nice. Yes, PET bottle. That PET bottle is polyethylene terephthalate bottle. Always remember. This is very common. Let me not give a hint. Let everyone, everyone has voted. Every plastic bottle has this. Recycle. Oh, that's so nice. Oh, cool. This is amazing. Photo, photo op. Okay, great. Ooh, that was, that was really, really close. Yeah. That was really close. No shuffling. Oh, no. Yes, pizza. It's very good. So, retro magnets can, so only, you know, 12 people were knowing it. That's cool. Not many people know this. Every, everywhere there is, wherever there is a motor, yes, the motor, you know, runs on electromagnetic principles. So, there has to be an electromagnet. Okay, everywhere, where there is a refrigerator, there is a compressor, right? So, there is electromagnet without those electromagnets. You can't run these machines. Okay. So, very good. So, you must know this next. Okay. Yes. This is the current position. Let's go to the next one. This, you must know. Every month, the person comes to your building or household and then he takes the reading. Yes, best come. Easy. So, you must be knowing this. This, this is taught also in the schools, right? Hmm, right? KWH, we call it, right? So, there's no what, there is no joule, K kilowatt R, right? Here, this is commercial unit of electrical energy. What is that? We, anyways, asked not kilowatt, Jami, kilowatt is power. So, kilowatt hour is, yes, KWH is the, so, you know, power is what? Energy by time. So, energy is power into time. So, power unit is kilowatt, time unit is hour. So, kilowatt hour. By the way, do you know how much energy India consumes or India can consume? India has the capability of consuming every second. Any idea? What is the total instant capacity in India? How much? No, nothing. What, what unit, Aditya? We have 300 plus or around 400 gigawatts power, 400 giga, 10 to the power 9, 400 into 10 to the power 9 watts, yeah, almost, not Tera giga, right? So, giga is 10 to the power 9, 400 gigawatts. So, in one second, if need be, India can consume 4 into 10 to the power 11 joules of energy in one second, in our country. We usually consume around 150, that is, you know, 1.5 into 10 to the power 12 joules of energy in one second, not 12, 10 to the power 11, 1.5 into 10 to the power 11 joules of energy, roughly. Okay. And you remember, there was this thing when it was announced to switch off the light at 9 o'clock in the evening, sometime back, some two weeks back, right? Then on that day, you know, so the lighting load of India is set. So, all lights put together, we have around 14 gigawatts. So, out of that 300 gigawatts, 14 is only on light, lighting. So, that's what, okay, next. He-haw, who is he-haw? He could not solve this one. Okay, next. Anika is maintaining the lead. Now, I don't know whether you know about this. How much do you pay for your electricity? Okay, very good. That's nice. So, you know, that's really cool that most of you know it, that you are paying this much amount of, did you really know it or you just guessed it? Right, have you seen your electricity bill? 0.79, that was way, no, I didn't. Did it come in the new newspaper? That I didn't know. Okay, very good. So, you know, so have you seen your electricity bill ever? What all details are there? Yeah, please check it, please check it once. What all details do you see there? There is RR number, there is this number, that number, how much kilowatt hour peak load, that load, this load. Try to understand and decipher each term. Let me see if you can, yeah, okay, great. Good to know that, that you know it. Next. Okay, cool. So, he-haw got it. And so is, okay, so not much change now. Not much change. Next question, guys, next question. Most of you know it. I actually gave this an example in the class. Okay, that's nice. Okay, most of you know it. Good, common sense, common, you know, you know, you know this already. But tell me one thing, why is it longest? Why is it longest? Why does it need to be the longest? Why does it need to be the longest? Why can't it be of the same length? What is the use, purpose? What surges on that? Surge meaning what? So, why do we need to be have, need to have this longest? Resistance to shock. What goes through the earth? So, longest. First to enter the electricity. First to enter the electricity. No. So, why is our thing needed? Is that if let's say there is any residual current on the body? Yes. First to connect and last to disconnect. Very aptly set, set, right? Very good. Why do you need to? Yes, that's fine. But why does it need to be the longest spin? It's because it has to be first to connect. Why? Because if at all there is any residual electricity on the surface of the equipment that you're using, so that electricity must go first and that should be removed. Hence, it should make the contact first before the live wire or live this thing comes into contact. Okay. Very good. Next. What is GFCI? Give full form here. I don't and how do you manage to spell your name wrong? Hey, come on. Next. So, Anika, very good. Well done. Let's see. Where does it go? Oh, ground fault circuit. GFC. Okay. This was easy. Mobile 4 charging adapter. Very good. Why do you need a transformer there? What does it do? What does the transformer do there? Any idea? Why is it required? Now that you know, most of your market correct, reduces voltage. Yes. Steps in down, right? So, step down. So, the, yes, to 5 volt. Very good. So, you don't require so much high voltage. So much high voltage, right? So, hence, okay? So, hence, what does it do is it takes 240 volt input to 20 to 240 volt input and reduces it to, reduce it to 5 volt. Now, transformer doesn't do AC to DC conversion. No. Okay. Yes. So, a phone cannot withstand charges. The cell phone cannot withstand that much. Yes. Very good. Nice. But then it doesn't convert AC to DC. For that, there is something called rectifier circuit, rectifier circuit converts AC to DC. Okay. Here is the next standing and my dear fellows, next. Don't know how many of you know this. So, cool. So, how did you like my options? My dear friends, all options, I had to think a lot to make such options. Harvard and Benetton. How did you, how was the name? The name was cool, right? Close. All the other three were fabricated. Okay. So, I tried my level best to make you get into trap, but then you guys are real interested. And my effort just went down the drain. No, not at all, Jhagraaf. I made it up. They are not real. Hardness and beauty, I'm laughing so. Right? Handwriting, right? So, handwriting and beauty of calligraphy. Maybe people can think like that. Okay. Okay. Next. Here. Oh, it seems Anika is way ahead. So, the only possibility is Anuya, you getting it right and Anika, you getting it wrong. KRM. Oh, Roshan is there. Cool. That's nice. Cool. KRM is on board. That's nice. Maintain that. Okay. The final question of the day. This is real stuff. How many of you know this? How many of you know this? You know, this is a big industry, very big industry. It's called e-waste industry. Oh, my God. Very, very less simple. One, two and three. So, you didn't add platinum. Everything is there. In fact, there is palladium, there is yes, there are all of them are present in the cell phones. So, it's a very big industry. It's called e-waste industry. In fact, your computers, especially mobile phones have all of this. Gold is a very good conductor of electricity. Gold and silver are the best conductors of electricity. Okay. So, that's yes. So, hence, these are used in very fine, very finite, sorry, very small quantity. You know, one more thing. All these, you know, and there are many more like palladium and many, many more. These are called rare earth metals. And which country holds the highest reserves of all this, you know, any, any guess. That country controls the economy of the world today. No, not at all. No, not at China. Correct. So, hence, China is like in the arm-twisting mode. So, they have lots of these, these, you know, if you see all your gadgets come from Taiwan, South Korea, North Korea, North Korea, North Korea is not that distinct. So, China, right? So, China is one country which supplies all your Apple iPhones, your MI ones, Lenovo. You name it and it is made out of, made out of China. Why? Because they are one good at, good at manufacturing. And second, they have all these, yes, all these rare earth metal. So, you guys need to be strong and competent, competent to beat these Chinese. Okay. So, that's why one reason why I'm teaching you all. Okay. Very good. So, this is the last, this was the last and final. Okay. So, Anika maintains the lead and Raja Jinagar, people have backed the first and third. Anika, many congratulations. Very good. You're really great. And Anuya, Pratik, Akshay, Ashish, Hiho, Ahan, Ronald, Nishant and Dhruv. Very good guys. So, I think, Point Alley wise, how many from Raja Jinagar? One, two, four, only three. So, eventually, Indranagar has more points than Raja Jinagar people in total this thing. Right. So, good. Congrats to all of you who have come into top 10. Right. Guys, did you like it? If you like this kind of quiz, then please put it as this thing in your group so that we can discuss it. Okay. So, if you want this kind of because this was just a trial with all of you. So, yes. So, we will have it more often. So, hence, you need to put it there in the, so that more people can come there and we can have more quizzes like that. Right. All well. So, please don't forget to mention one line about this so that we can attract more people. Okay. That's the only intention not to gain any brownie points over here. But just to make sure that everyone takes part. So, just put a couple of lines there in the group that you like the quiz so that we can, we get some motivation to work more hard and get some more questions on this. Okay. Thanks guys. And I hope you really enjoyed it. We will learn like this. Quizzing is the best way of learning, I think. So, thanks for participating in. Congrats, Anika. Once again, well done, buddy. Keep it up. Bharath Pill will try and sort it out, buddy. Sorry.
