Hi, in the given problem here there is a multi -loop circuit.
00:09
The first loop is having a resistance of 6 .00 om and it is carrying a current 1 .00 ampere in upward direction.
00:28
It is also carrying a battery, it is also having a battery of unknown emf.
00:37
So this is first loop.
00:40
The middle branch is having a resistance 4 .00 om, the current i passing through it, and a battery of emf 125 volt.
00:58
Finally, the second loop is closed by another resistance having a value of 10 .00.
01:08
The value of this resistance is not given to us.
01:13
We have to find it.
01:15
This is r, the unknown resistance.
01:20
And the current passing through this resistance has been given as 10 .00 amper.
01:26
So here the emf and the resistance, these two are unknown which we have to find.
01:33
Naming of the loop a, b, c, c...
