Homework Help: Two small circuit questions

  1. Apr 21, 2014 #1
    1. The problem statement, all variables and given/known data

    Is it possible to simplify the first circuit?
    And for the second circuit, does every other component in the circuit have 6A?

    2. Relevant equations

    3. The attempt at a solution

    The first circuit can be simplified.

    There's not nearly enough information given here.

    You should give a complete statement regarding the problem(s) you're trying to solve.

    Also, you need to make an attempt at a solution.

    For the first, is the equivalent resistance the parallel combination of R2 and R3 since the voltage of R1 is 0? Does R1 get used at all?

    And for the second, I forgot to include that the circle with an arrow inside is a current source providing 6A
