Homework Help: Super Position

  1. Oct 26, 2007 #1
    1. The problem statement, all variables and given/known data

    Solve for all of the currents using superposition.

    2. Relevant equations
    Remove the one source and solve the problem in two steps.



    3. The attempt at a solution

    Ive isolated each source separately but once i get to that point im completely stumped on what route to take. I know i could probably use node eq's but im not sure if thats the best way to go about solving it?

    Doesn't the principle of superposition deal with multiple sources? Where is the other source in your circuit? Have you shown it removed with a short?

    Woops! yes there is another 9V source in series with R5, below it.

    Mesh currents might be a quicker route to your answer, since you are trying to solve for current. I would also combine R2 and R3 just to knock out a few numbers from the start.
