In this question we are given a circuit and we have to find out the potential drop across each of the register azula's current passing through it.
00:12
So this is the figure where we can see that our potential is e across the registers.
00:20
So we have to find out potential drop across each of them.
00:24
For which, say the current for this loop 1 v.
00:31
I1 and current from loop 2 is i2 this is our loop 1 this is our loop 2 so for loop 1 we can write the kitchups equation as e minus i 1 r minus i 1 and 3r and there is also i 2 so the r4, that's why we can write it plus i2 into 3r equal to 0.
01:27
That implies we got here minus 4 i1r plus 3 i2r plus e equals 0.
01:47
That implies 4 i1r minus 3 i 2r minus e equals 0.
02:03
It's our equation 1.
02:06
Now for loop 2 we can write that there is no voltage that's why i2 minus i 2r 3r i 2r minus i 2r minus i 2r again i1 also passes so, r4, that's why, plus i1, 3r equals 0...
