Okay, so we have this circuit.
00:04
Notice we have a dependent source.
00:06
We're told that the power in the dependent source is 230 watts.
00:12
Our goal is to find the voltage in this source over here.
00:17
I'm going to define some more currents.
00:40
All right.
00:44
So let's write out some equations.
00:48
Oh, and by the way, the power in the dependent source, that's equal to the voltage, which is 5i3, times the power.
01:11
Current, which is i1.
01:17
So that's actually one of our equations that we're going to have to solve.
01:23
All right.
01:24
Let's look atjunctions.
01:30
All right.
02:43
So we get two more equations from voltage law loops.
02:48
So i'm going to call this one.
02:54
That's going to be loop one.
02:56
So i can't include a current source in a voltage law loop because i don't know what is voltage is, although i do need...
