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.
