Hello students, here we have to calculate the current passing through each resistor and from this we have to calculate power in each resistor.
00:07
So first consider the current i1 is passing from the 20 volt power supply and from this we can write the current is divided into i2, i3 and the current passing from this power supply is i4.
00:27
So first of all consider the loop a, b, c, d and e, f, g, h.
00:45
So first we can consider the loop of ad, eh.
00:58
We will get the equation as 20 equal to 6i1 plus 6i3.
01:10
So here i3 equal to i1 plus i2.
01:15
We will get 6i1 plus 6i1 plus 6i2.
01:23
So we will get 12i1 plus 6i2.
01:27
This is our equation number 2.
01:29
Similarly for the inner loop we will get 12i1.
01:42
We will get 50 equal to 6i2 plus 6i3.
01:53
So solving it we will get 50 equal to 12i3 plus 6i1.
02:01
So this is our equation number 3...
