1. The problem statement, all variables and given/known data
The Question is number 18 in this link: http://www.sewanee.edu/physics/PHYSICS102/Ch28.pdf [Broken]

3. The attempt at a solution
I Used X,Y,Z for currents.
X for the segment straight down the middle.
Y for the bottom to top segment on the left
Z for the bottom to top segment on the right
WHat i got was:
X: -.5
Y: .5
Z: 0
but these are wrong, since it doesn't lead to the correct answer which is (-5)
can you tell me what currents you have?

I looked at this problem yesterday and thought I had done something wrong. I got zero current flowing through the 10V battery on that side of the circuit and 0.5 amps on the other side? I did come up with the correct answer but I was attempting to use my ideas about DC circuits and Kirchoffs rules and I cannot quite explain to myself why there is no current on the left hand side or through the 10v battery. Can anyone explain? I am sorry to interject on another persons question. If I should go back and repost I will. I just wanted an explaination.

Oh snap... I just figured it out... sorry. Continue.
