All right, so let's say we have a circuit with a 24 -volt battery connected to two resistors like this.
00:09
And then there's a third path with another resistor.
00:13
But this is connected to another battery with another series of resistors.
00:20
And we have a current i -1 going through this loop, a current i -2 going through this loop.
00:27
We're told this is 24 volts.
00:29
We're not told the voltage here.
00:31
But we're told this is 5 oms.
00:36
Let's see.
00:38
And, or sorry, v, we actually are told it.
00:40
It's 11 volts.
00:42
This is 2 .1 oms.
00:45
This is 4 oms.
00:47
This bottom resistor is 3 oms.
00:50
And then what am i missing? this middle one, r2, we're told is 1 .4...
