Homework Help: Source Transformation Question

  1. Jul 10, 2010 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    v = r * i


    3. The attempt at a solution

    Having issues with the left box I think. I have been starting on the right side and working left by first starting with the 5A current source. I guess I'm having issues with the circuit placement after the transformation and how it ends up turning out once you get to the left box which I believe isn't in series at all.

    It's actually more straightforward to start from the left. The left most source (+9V with two 4 ohm resistors) can be eliminated because the -9V voltage source will force the node to a fixed voltage no matter what the +9V source current is.
