RLC circuits

  1. Jan 17, 2006 #1
    I have a problem with an RLC circuit. It consists of a resistor in series, followed by another resistor, capacitor, and inducer, all in parallel.
    The question is asking for what frequency (its an AC circuit), is the current through the inducer the same as the resistor (the one in parallel).
    Im unsure how to set up the problem... do i use Kirchoffs loop rule?? Or use impedances?
    Any help would be appreciated

    I would use impedances. Set up the equations for the various currents in terms of jw. You can use the equations for parallel impedances and then the voltage divider equation. Then at the end you just set the resistor and the incudtor currents equal and solve for w.
