Homework Help: Kirchoff's loop rule for AC

  1. Mar 2, 2007 #1
    I was wondering why Kirchoff's loop rule holds for the complex representations of voltage drops in AC circuits. That is, sum of complex voltage drops = 0.

    I tried working it out from Kirchoff's rule in DC, but am not sure how to proceed properly.

    The loop rule is a statement of conservation of energy.
