This problem is a parallel circuit, so i'm going to use kirchhoff's current law.
00:05
It says that for any node, some of the currents in and out is equal to zero.
00:09
I'm also going to use the understanding that the voltage drop across each branch is identical, and in this problem, that is labeled as v .1 over on the left -hand side.
00:22
So i can pick a node and apply kirchhoff's current law, and i'll just do it there at the first node in the top left, and that's where i have i sub x coming out.
00:33
I'm going to say that i have v .1 over 6 kilooms.
00:40
That's the current coming out going into that left hand side.
00:46
So i'll call that positive.
00:48
And then i have minus 6 milanps, so 6 over k.
00:54
So that's coming in.
00:56
Then going out, i have 3 times...
