Homework Help: Source Superposition

  1. Sep 28, 2010 #1
    1. The problem statement, all variables and given/known data

    This isn't a homework assignment, this is straight from the textbook. They work it out but I'm still not following, would it be possible for someone to go through this step by step and explain
    it clearly? (How to determine the current due to the voltage source and due to the current source.) I can get the right answer when it comes to determining the current due to the voltage source but the current source trips me up. Thanks.


    2. Relevant equations



    3. The attempt at a solution

    For the current source drawing (b): You have 6 A going into the junction. How is the current split between the two resistors? Note that they share the same voltage. Are they in series or in parallel?
    For the voltage source (c): You have two resistors that share the same current. How much current do they draw? Are they in series or in parallel?

    Thanks. My big problem was not realizing I had to convert the current source into a voltage source by placing the parallel resistor in series.
