  1. Oct 15, 2011 #1
    1. The problem statement, all variables and given/known data

    http://i52.tinypic.com/11loqy0.png

    Find Va,Vb,Vab and current flowing from V1.(a,b,ab are subscripts.)

    2. Relevant equations
    hmm like
    Vx=Rx/Rt x E


    3. The attempt at a solution


    i can find voltages across resistors but i dunt know how to find voltages across points.
