V=IR
The Attempt at a Solution
I believe my a1 and a2 are correct.
But my b1 is definitely wrong. Even if I carry out the above subtraction for the v1 part (which gives you b1) I will not have somethign as simple as R2 + R3 on the numerator
[/B]
Where would be some starting places to pinpoint the error?
