Homework Help: Current in Circuit Problem

  1. May 22, 2010 #1
    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?

    Hi GlobalDuty! :wink:
    (on page 6)

    Show us your full calculations, and then we'll see what went wrong, and we'll know how to help! :smile:

    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.
