00:01
So we need to find the current in branch of the circuit given here.
00:04
So we can use kitchhaw's law, that is summation of voltages or electric potential is zero over a loop.
00:13
So here we have three loops.
00:15
One is this one, second this, and the third one is the bigger cycle.
00:21
So let's start solving this with this loop.
00:25
So here let's move in this direction.
00:27
So when we go from positive negative terminal to positive terminal, there is rise in voltage.
00:35
We'll take it as plus.
00:37
Then there is i1 current here, but there is no resistance, so there is no voltage drop.
00:42
Now we move inside here...
