Current, Power, and Energy problem

  1. Oct 21, 2005 #1
    Okay, here's the problem:
    http://www.ihostphotos.com/show.php?id=174911

    Already did it once, but then I realized my "method" :rolleyes: looked good, but wasn't correct. Is there two loops for this problem, to start, or what? I get the formulas and the laws, but something is throwing me as to starting it.

    ANYBODY think it looks correct? I'm confident on the first part, but just wondering about my answers to parts b) and c).

    It is a little complicated to analyse this circuit but your answer cannot be right. Without R1 the current through the ammeter would be 5 amps. With R1 the current will be less.
