Homework Help: Help, RLC Circuit Problem - Peak Current At Resonance

  1. Apr 20, 2008 #1
    1. The problem statement, all variables and given/known data

    A 5 Micro-F Capacitor, a 65mH Inductor, and a 10 Ohm resistor are connected in series
    Find the resonant frequency of this circuit.
    Determine the peak current at resonance, if the peak voltage is 100V

    2. Relevant equations

    Fr = (1/2Pi) Square Root(1/LC)
    I don't know the equation for Peak Current ... HELP!

    3. The attempt at a solution

    Resonant Frequency = 883 Hertz
    Maximum Current = 10 Amps

    You should have calculated the peak current by doing:
    [tex] I_{peak} = \frac{V_{peak}}{Z_{total}} [/tex]
    Where Z_total is the total impedance of the circuit.
