 This is 5 volt battery, this is 2 ohms, this is 2 ohms, 1 ohm, 4 ohm, and 4 ohms, okay? This is A, this is B, this is C, why I am naming all of this, that's all. For example, suppose from here current I1 comes, okay? Current, you can start from anywhere, you can say, okay, following junction rule, it doesn't matter, fine? So current starts from here, now this current, I do go into this current, 2 minus I3, okay? What about this current? How much this will be? Sir, we want I2 minus I1, minus I1, okay? Now check here, is junction rule satisfied in this junction? Current coming in is all, so is it satisfying? Are you sure? I1 minus I2 becomes 0, okay? So junction rule is satisfied, now are you sure? So we will just write down equation for these 3 loops, then these 3, that equation will be, okay? So first step is to write down equation for loop 1, loop 2, and loop 3, and then solve that, follow junction rule, fine? And if that direction is not correct, the final answer you may get is... What do you mean? 1, 2, and 3, have 3ong problems, isn't it? No, no, no, no, no. I'm deloting here by multiplying with my direction changes, it doesn't matter. Okay, very neatly, loop number 1, okay? In a nice handwriting expression, then for loop number 2, and root number 3, not so nice to me. I am anyway writing down. You can write down what you understand. Okay, let us start. Let's see. So what should I write? I have reached point number C. So this would be equal to 0. How many of you got this correct first attempt? Sir, I did it completely as one. How many of you got 10 times as I1? So you do it. Then what should I write? So plus 4 times plus 1 into I1. This is I1 equals to 0. How about number 3? What should I write? Plus 2 into? Then? Minus 5. Minus 5. Plus 2 into? I2 minus I2. I2 minus I2. So this is B of solving these type of equations. So a lot of error happens. So right now these are the three given in front of you. All of you, please solve these three. So get I1, I2 and I3. Sir, what will be minus 5 I1? Minus 5. This is bad thing, it is not resistance. This one? Because I am going from C upwards. I am going like this, isn't it? So C is A, I am going to B. So I am going again in the direction of I1. See I2 minus I3 is coming like this. And this is I1. So this becomes I2 minus I3. So the junction rule is followed. Now solve these three equations and get the answer. Let us see if all of you get the same answer. It has never happened past 6-7 years that all the students got the same answer. This is a challenge for you and get the same correct answer. Although probability of getting the same wrong answer. Because there are so many wrong answers. So we have to... Tell me. I1 is I1 minus 5. I1 is I4. I2. 5 by 4, can you see where it is flying? I1. Yes, 5 by 2. I2 is? 5 by 8. Yes. I2 is 5 by 8. 5 by 8. you start getting answers. So, I should do that whatever I just feel right. So, I should find reasons to shuffle. We will do one more question similar so that you understand properly. Any one of you did not understand the previous one. You got the answer? Yes sir, you got it? I'll try to do this question. So, how much is the branch? Can you find out? This one is what? Use Jensen's rule. I will come in from here. Now check with it. So, everywhere Jensen's rule if we lose you see here. Actually the one rule can also be wrong. That can be five or six. But then if you see one is this, other is that and this one. So, I'll just name them so that we all follow the same thing. You write down the Kirchhoff's loop rule equation for one, two and three. Write down equation and we are done. So, very neatly write down the equation for loop one, two. Should we write it now? Three is like this. What? Three is like this. Three is this smaller one. I am taking only elementary loops. I am not comparing anything. How many equations are you using by the way? I will write it down. Okay, let us write it down. Let's start from A. Sir, you are negative. Yes, then you are negative. Let's write it down. Minus five. Minus five into i minus i plus ten. Minus. Minus 60 into i1. Fine. All of you got this equation? Yes, sir. Solve it. Sir, from A, what kind of equation are you using by the way? I am going like this. Minus five into i minus i. I am going against the other. Minus. Along the diagonal minus. Minus. For resistance. Sir, you see not just looking at the diagonal current. Oh, the center. Yes. Yeah, there will be minus. Yeah, we got this positive. Which one? Yeah, we are going to do one.
