Homework Help: Basic KCL Problem

  1. May 4, 2014 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations


    3. The attempt at a solution


    At node a: 6= io + Is
    At node b: Is= io/4 + I8

    Couldn't go much further.

    two things to note:

    1.)a and b can be considered the same node as their voltage is the same.

    2.)Also for calculating values such as I8 and Io, remember ohms law. V=IR
    try to use that relationship to finish your equation.

    Vo=I8*8, Vo=Io*2 --> Vo=Vo, I8*8=Io*2 --> I8=Io/4?

    So now you can solve for Io and Vo...
