To Determine the Resistance of the galvanometer by Half Deflection Method and find figure of Merit

You'll definitely enjoy watching this channel, and there are also lectures uploaded by you. Come on. You too will be given very, very, very much to do. But I'll bring the lab equipment and demonstrate practically how these things work, so you'll clearly understand that you need to find the focal length of the convex lens using the half-deflection method, and also determine its figure of merit. Don't you want to take a look at the circuit diagram? You used to struggle with the game, like those who were guarding the box, constantly fighting over the guarded box. Even on Facebook, the treatment we can now afford to give them is something we can finally play with. Now we understand Grenb. I will connect you to the glory meter and take the reading now. So, in my glory meter, I get 28 readings. So I'm the one with this small one When connected to the resistance box If I check it, the reading will be completely halved. So, the player said the words from the glory matter. It's not about the people; it's about the matter. Do you have a terminal from the resistance box? Will you connect? Then it will go there. Sold to you on the spot I'll make it clear to Konik that it's different from the previous one. From before This is my key one and this is key two. Alright Alright, I'll connect this here. Alright After that, the second terminal of your key So I've connected it here. Connect the second one as well. From the negative terminal of the battery Now let's see, this galonometer of yours, kid It will perform deflection from 0 to 30 here. So, the deflection I'll show you will be halved. Thita, in order to perform Thita, must be made with a specific type of cloth. And I will show you half of the truth. This is the experiment we have been conducting. Hap cell, show hap deflection, okay, so how will it be, so this is your second Who are these people? The second one, the kid with the resistance box, he does this and gives it to you right here. She was coming, how many were coming... 28, how many cows were coming... 28, oh, appuskeh pad What do you have to do? The child is crying, what do you have to do, because this is a bit confusing. Now what you have to do is remove the resistance from the S. And let's see whether we can get half of it to work. This is exactly the hippocampus dentate gyrus, you need to demonstrate the hippocampus by highlighting the dentate gyrus here. I need to check on the hap, then look after the rot. I've checked, it's not gone, it's been fifteen. Okay, I'll do one thing now. How much has it become? It's become 14. Okay, so check the previous. My reading was 28. Now I've got 50, 50, 60, and this ten is not 50, 60, 70, and one 80, so So, from the boys, remove 80. So, my half has become this. Half means how much, it came to my 14 theta over 2 I'm here, my boy, this is your brother, 2 So this means that when you calculate these large resistor values, you will be getting Then, with the galvanometer, you will close K1. What are you going to do with K2, are you going to open it? But when you remove S from the resistance box and check it, you'll have to do it from S. Whether these values are half or not Both of them will have to be closed for this. And whatever is here will have to be seen from here. How much are you having to take out to halve this? So I had to find the 80-ohm resistor again. How much will my value be half a step ahead at 14? Alright, we can handle that part afterwards. Let's see after that, and we'll ask him. I mean, these will be the circuits. Alright, we will remove K1 and K2 from the back. Alright, we will now turn on the circuit. And we will close K1 back. How much they are showing us 28 are showing You will take 2-3 readings of the combustion chamber. So we will take the deflections in pairs of two. I mean, it's 28, so I'll make it 26. So if I take out 200 200 taken out Brother, it's a bit too little. I will do a task. I won't take out 200. Come on, just arrived How much did this bring in? 25–26 Now I have figured out how much 5-6-7-8-9 I mean, I had 900 Resistance has been removed here. from the resistance box So how much have I received? 25 And these 26 If I withdraw 1000 I'm doing two by two I take resistance into account So, how much has this come to me? When I saw the 900 500-200-200 You must be able to see this from here. You can see it, can't you? You can see the values So when I had You took out that much, then you were there You can see it here How much has this value come to? It's already 28. How much has it come, kid? 28 26 25-26 I also came for accounting Now what should I do? I'll close K2. I will close K2 only when the child does so So this value should become half What have I done to K2 now? So how much has come for me? 13 Look, these 10 11-12-13, so it's you What value has come? So I didn't have to change it. I have a resistance. Some of these Taken out And I've fixed that resistance. That's what's being used by everyone for me. How much did you get? Now we We remove all of them. We will remove all of them. And what will we do now? In the large resistance box Extract even more value from it One more me I will close it. Because me I need the value of the large resistance box. So, this filal is showing 26 Now I'll reduce it by two more. 24 Now show me, I've reached 24 So for 1000 If you pay the account, how much have I received for 1000? 24 Alright, look here And this one with the belly is 100. Alright, so how much will it be? So, for this, I've got 24. I take out 50 But the entire thing will have to be removed. I'll take it out here. How much is 50 Two less than 50 has been deducted. 20 21 Pulled out here Meaning 1050 How much has been received? 20 22 And if I close it If I close this So I have 80 I don't feel like changing this. I'm getting 11 milli at 80 ohms How much is being received? 11 What comes after 11? Pay me this Pay, if I have this 20 Do it When I am How much? Does How much r x s 800 x s 80 64,000 r-s 800-80 720 64,000 720 88.8 r-s 72,000 72,000 820 87.8 1000 x 800 8000 80 80,000 80,000 × 920 86.9 1050 x 80 84,000 84,000 x 84,000 970 Is what's coming to me, correct? What's the value coming for everyone? She's coming, right? Now, don't connect all of you together Oh, divide by four after joining everyone. So 86.9 Plus 87.8 Plus 88.8 Badiaet Bap 4 How much have I got? Yes Now let's see what we need to do next. EMF of the battery cell I had taken 2 volts in the eliminator. So, what was my resistance value? Yes, it was 800. Here I can, it was 800 OK? The second one was 900. Aryar, it was 800, not 1000 1000 1050 How much was Theta coming to me? Yes, 28 was coming. It was coming at 26 It was coming at 24. It was coming. How are you going to do this now? How are you going to get it? So E divided by R plus G into theta How much is R? Tell me, please? Yes, what is R? R is mine, it's 800. Lass, G What is G? Yes, what is it? That is 87.52 Okay? 887 arrived By what number should 887 be multiplied? From Theta What is the value of theta? 28 OK? Here it is, 24,850 Yes, how much has it come to? 24,850 So 2 divided by 24,850 24, 2 divided by 24, 850 So how much will this cost me? 0.0000 One, one minute One, two, three, four Four, zero is So I'm raising this to 10 raised to I convert that is One, two, three, four, five I mean, I can do this. 8.048 times 10 to the minus 5 OK? Now the same way You will also have to multiply this. What else? So, he said to me 900, how much is that? 87.52 Okay? 987, 987 Now 2 divided by 987 2 divided by 987 equals approximately 0.002026342. I haven't added the value of theta at all. 987 into Isn't there also Theta? How much is theta here, kid? 26 What is my theta for the second value? 87 Okay? So 26 So it will come here today 5 25662 2566 This means 2 divided by 25662 Okay? So, how much will this cost me? I will write it after converting. One, two, three, four, five 7.79 10 to the power of minus 5 Let's do the next one thenMODIFIED that is R plus G R plus R, this is mine g This is it OK? So 1000 1000 plus 87.5 87.5 752 OK? Now it's time to do it Multiply by theta What is my theta? 24 OK? 24 OK? So how much will it be today? 28 119 2819 So 2 divided by 2 divided by 28 119 OK? So how much will it be today? 7.11 10 to the power of minus 5 How much will it be now? This 1050 plus 87.52 1137 What is theta? 22 OK? 25025 So 2 divided by 25025 Okay? So how much will it be today? 7.99 10 to the power of minus 5 Okay? Now you will connect everyone Divide by two And the figure of merits Will come today OK? mean value of figure of merit of galvanometry Your figure of What does it mean? I forgot to mention it at the beginning. What does KK mean? Your figure of merit That's the one we took out. This is the formula for figure of merit E plus R G Okay? To deviate 1, 2, 3, 4, 5 So divide by 5 Okay? 1, 2, 3, 4, wasn't it? How much is left? 123, 4 is, sorry. How much will it come to? Yes. So the mean that we are getting that is ours I am writing here 7.7 7.73 into 10 to the power of minus 5 What has become of my marriage? 7.73 × 10⁻⁵ This is the entire overview of the experiment. This is the entire experiment's In the Moon Mento, this battery eliminator will be given to you. You can remove even the figure of marriage; what else can you do? How do you find this experiment's child? Please definitely let me know the video, I'll show you even more tricks on the board. When I connect the second resistance box to it, Please definitely tell the video, I feel like a child experimenting. I am certainly letting you know about this family. I'm just trying to get you to notice the child. So that I can move a little further ahead and bring you a few more things You'll answer my question, won't you, all the children And please do subscribe to ATJ Practicals, thank you
