In this problem, we have this circuit.
00:02
Now you want to find the current i2 and i3.
00:05
And we're given current 1 is 3 amps.
00:12
And to do this, we use what's called croco's loop law, which is the sum of the voltages in a given part of the circuit or the entire circuit is equal to 0.
00:24
And we also use holmes law for each individual voltage, which is voltage is equal to current.
00:31
Times resistance.
00:33
So we pick the direction of the positive current, and from there we write down each voltage for each individual circuit element.
00:42
We have it equal to zero, and then we can solve for whatever current we're looking for.
00:47
So for this case, we can just look at the right part of this circuit.
00:51
We can say the positive current is flowing in this direction.
00:58
So when we use could cause loop law, the positive current is going to flow from the negative to the positive terminal of the battery at the top.
01:07
So that means we have a positive 24 volts...
