Homework Help: Node Analysis

  1. Oct 4, 2007 #1
    1. The problem statement, all variables and given/known data
    Find the voltages at V1 V2 & V3 in the attached circuit using node analysis.

    2. Relevant equations

    Node analysis

    3. The attempt at a solution

    I came up with a few equations for the variables:


    Solving I get V1:7.33V
    I think I did it right but i dont see how i can get -26V when theres only 12 to begin with??

    The voltage source is not the only source of current.
    There are constant current sources involved in the circuit as well. So there would be situations of V= I(current from voltage source + current from constant current source)R.
