Okay, so we're supposed to find, to use a series of source transformations to find the voltage v0.
00:09
All right.
00:10
So we have several steps here.
00:12
So first of all, let's take this.
00:16
So whenever we have a current source that's in parallel with a voltage, with a resistance, we can transform that.
00:28
And it transforms into something that looks like this.
00:58
And then the voltage of this source is i times r.
01:05
So that's 8k times 2 .5 milli amps.
01:11
The k and the millie cancel out.
01:15
We're left over with 20 volts.
01:22
And then we have this.
01:44
You might say, well, gee, can't you transform this? and you can.
01:48
I'm just not going to yet.
01:51
All right.
01:52
But i am going to transform this set.
02:01
So we got, well, that's 5, that's 60...
