In this problem, we are asked to solve for voltage v.
00:04
A in a series dc circuit.
00:09
To do this, we're going to use kirchhoff's voltage law, abbreviated kbl.
00:16
Kerchhoff's voltage law states that the sum of the voltage drops around any closed loop is equal to zero.
00:23
To solve this problem, we're going to create two loops.
00:28
One loop on the right, going around this way, we're going to call loop one.
00:38
The second loop on the left side of the circuit, going around this way, we're going to call loop two.
00:54
Fortunately, to help solve this problem, someone measured the voltage between point a and point b, and that's four volts.

And that's going to become very handy...
