## The Attempt at a Solution

(a)

In the left loop :

-8-12+VR2 = 0

VR2 = -20 v

(b)

In the big loop :

-8-12+7-9-V2-3+VR1 = 0

-8-12+7-9-V2-3+1 = 0

V2 = -24

Why is my solution wrong?

If I take the right loop for (b) using the right answer for (a) :

-4+7-9-V2-3+1 = 0

V2 = -8 which is true.

Is the wrong with the negative voltage (-8) ??

thanks.
