Law of resistance using metre Bridge experiment || 12th physics practical @a2zpractical991

Today we are going to carry out some practical sessions, such as Experiment Number 8. Law of resistance using meter bridge You must have a lot of doubts about the meter bridge experiment in MATLAB, I know that. Whether to connect things in a series or in parallel You have so many doubts. Today I will clarify those doubts here. Let me show you very clearly how to handle the instruments. Because you have too many problems in handling it. This experiment is likely to come in your board examination. Okay, let's go Let me explain a few things to you. As you can see this circuit diagram What do you see in this circuit diagram? You are his X. You're a mystery to me, your unknown resistance This is basically how a unknown resistance works with you. I'm telling you about the series first. Then, does this unknown resistance directly connect to your what? Yes What happens when connected through this terminal? What is the unknown resistance here for both of these two? After that, it's connected. After that is the battery here. Just show me the positive and negative of the battery The positive terminal of the battery is connected to one end of the meter bridge. Look here, this is the positive terminal of the battery; it is connected to one end of the meter bridge. This negative terminal of the battery is connected to your key. Look here, to which one is this negative terminal connected? Yes The key is connected. The other terminal, which is key, connects you to the rear store. I'm locking this now. Okay The key that connects to the second terminal is connected to a terminal of the rear store. And that is the common one Alright, we'll take the upper one then. Which terminal is the Doosra terminal connected to? Yes It is connected to your meter bridge. Others are here already Okay After that, there is a resistance box here. That's a known resistance box. Okay, you know all his values. After that, the next one arrives On the galvanometer The B column that you are seeing The one end of the galvanometer that remains You need to connect to this. Like a meter bridge Just look, I've got this one end here It is connected here from the meter bridge. The negative end of the galvanometer, you know, the negative one The jockey is connected. Look at this This is the other end of the galvanometer. Who are you connected to? The jockey is connected. Ab's experiments me Has been given. Okay Here, I'm turning it on for him. Okay If you're going to do it, then save the connection You must always keep one thing in mind Alright, students, you need to pay attention to one thing Whenever you connect So you're just one terminal Matlab right-hand side if you're touching it When the galvanometer shows deflection to the right side And as you touch the child on the left side The galvanometer's deflection You should be shown on the left side If I just let this go If this comes up in the middle So what is that called? Null deflection Okay, let's go Start reading now So, what was it that you were supposed to do in reading? If you are here for the observation table They're just looking at you. You must have understood this by now Ki There are connections here. I had to connect to a series. And another series in a left gap You are the second series in a right gap Look carefully Look, I've taken an unknown resistance here And this is our place, yes Left me gap Aur left gap me bacha aapko teen reading nikalni hoti So, how do I figure it out in the first reading? I won't pick number 10 from the known resistances here. What can I do with the known resistance? I'll take out 10 When I remove it on the 10th After that, what should you do? You have to tap it. If I tap here It's showing deflection over here. Okay Look here Here it is Okay 70 pcs 70, my first reading has arrived How much null deflection is being shown here? I can't see it. This makes me feel like I'm reading something from you. You connected the left side. You will count the number on the left side. Okay I'm getting 0 on 70. The first LX reading that comes up is what's left. I am 70 years old. You can find out the LR yourself 70 means 70 minus 100 minus 70 will be You will receive the LR reading. Okay And that's it XS MATLAB Series unknown resistance For series How much is the R value for Toh? 10 Because I pulled out how much resistance 10 LX can be done by LR Divide and conquer. Liks sakto pehli You need to pick 3 readings How to get out I just removed 10 out. I'm here now 20 stolen How do I get rid of 20? Look This is the 20th column coming out from here. I'll close the one at 10. How much did you withdraw from the ATM? Back again from here What should I do with the jockey? I'll tap it. Okay Toh philal I'm getting 54 here. Doosra reading What a kid You need to take out 3 readings After that On the left side, the one that is Unknown resistance applied I want to get rid of you. Temple On the right side of me To place it The known resistance is that Boy His left hand It must be exited from the right side. Alright On the left side me I need to place it. Okay Matlab will come here today He will come here today. Just do it this way Same to you again Just look here He's come here again. So you're always You'll look at this reading Okay If it has come here You'll look at the reading over here Where are you, dear? Null deflection aata You will write this value What is LR? You will subtract from 100 Okay Done it. The other one is in it That's what I did You That's what I did You are series in the Provided the combination But now What do you need to do? I want to connect in parallel Series of Unknown resistance How to connect it Yes Here, here Looked at with concentration Look at this Looked at with concentration You are here What will they understand? That's absolutely Connect in parallel with it Look, this is here Connected And this is here Hello Here it is Hello And this is here Connected Certainly, you can establish this connection. Look Connect it in parallel Bolte Okay Just as you have Previous experiment Wasn't it? In the series of this Do it the same way. MATLAB Once upon a time On the left side To connect The one known on the right side After that It has to be removed again. On the left side To connect Now we need to remove it To the right side of it To connect After that You too Tinti is reading Leni. If you leave me this way Will you connect then? And when you do it on the right side Will you connect then? Do you have tinti reading? What to do, where to go After that Last me aapko Unknown resistance For series An unknown resistance For parallel Last me This calculation here You must be seeing You must be seeing it right above you. Certainly You need to put the value here. X and Y of X1 X2 You know it Where can it be obtained? From here From here, you Values of series and parallel It is a thousand. So here it is You were supposed to put it down. And you will get the answer After that What is X1 X2? You must know X1 Look at this Maine 10 ohms ka 20 ohms 10 ohms for one For 20 ohms The values of X1 and X2 That is ours. 10 and 20 How much will the total be? 30 These very values to you Put it here We need to find the answer. If you How much was obtained through practicals? When you practically What? How much was collected? And by theory When I saw it That's 30 ohms, right? Therefore, the complete answer Your 30 ohms It should come right away. Look That's very easy indeed. It's an experiment. Law of Resistance Using a meter bridge Child If you have anything else So many of these Experiment on Quick revision Need And many more islands You are doing it, Galatia To use related Any kind of chichiye will be available In the video's comment section To give Main aapke liye This video will be uploaded.
