Homework Help: Nodal Analysis: Imaginary Numbers

  1. Apr 12, 2014 #1
    1. The problem statement, all variables and given/known data

    I have to find the Thevinin Equivalent for the following circuit.


    I am assuming the current is going out of the node.
    V= node between inductor and capacitor
    V0 = V[40/(40-150j)]

    (V-75)/(600+150j) + (-0.02V0) + V/(40-150j) = 0

    The only problem I have is with the last part of the equation, is the one I have right or is it (V-V0)/-150j

    Maybe they're both right! Solve both ways & see!

    Ok I solved just the last part two different ways since it was the only different part in the equation, and I got the same answers.

    0.0016597 - 0.007109j

    Is this supposed to be Vo?

    I get a much larger result for Vo.

    No that is just the last part of the equation, V/(40-150j) which is same as (V-V0/-150j
    This means I can use either of these two, which was my original question.

    So what's your final result?
