Homework Help: LRC circuits

  1. Apr 20, 2009 #1
    1. The problem statement, all variables and given/known data

    An LRC series circuit with R = 200!, L = 32mH, and C = 2.5μF is
    powered by an ac voltage source of peak voltageV0 = 200V and frequency
    f = 770Hz. Determine the peak current that flows in this circuit.

    2. Relevant equations

    V= IR

    -L dI/dT +Q/C = 0

    w = 2 pi f

    3. The attempt at a solution

    -.032 H- IR+ Q/c = 0

    Hi bgav88,

    What's the relationship between peak current and peak voltage for an AC circuit?

    (For a DC circuit you would use Ohm's law; what similar equation applies here?)
