Okay, we want to solve this circuit.
00:04
I'm going to define some unknown currents like that.
00:13
I know that some of them are going to be negative.
00:15
I'm actually suspicious.
00:17
I think ix is going to be negative.
00:19
We do have a dependent current source over here.
00:25
So i'm going to label these junctions a, b, and c.
00:34
So we got three junction rules.
00:37
There is a fourth one along the bottom, but it's not linearly independent of the others.
00:44
So we got at b, we got i2 plus 5ix3.
01:03
And at junction c, we got ix plus i3 is equal to 1.
01:17
That's a 1 -amp source.
01:21
Okay? and then there's actually only one loop.
01:30
And that loop goes like this.
01:37
Because you can't include a current source in any branch along a loop...
