DC Circuit Questions

  1. Apr 6, 2016 #1
    1. The problem statement, all variables and given/known data

    There is a current of 3.2A flowing through the 20.0ohm resistor...(the questions along with my work are attached below).
    I am having some trouble with DC circuits, especially those that include a combination of series and parallel circuits. I have worked through the problem, but do not know if I am on the right track and are correct in my answers. Any help is very much appreciated!

    2. Relevant equations
    Ohm's Law: V=IR
    1/Req = 1/R1 + 1/R2 ...

    3. The attempt at a solution
    Attached below.

    I agree. All correct and pretty much using the best methods.

    For question c) you used Kirchhoff's Current Law. It would also be possible to use that and the symmetry of the problem to answer question g.
