Homework Help: Inductance and current

  1. Nov 19, 2007 #1
    An RLC circuit consists of a 48 ohm resistor, a 200 uF capacitor, and an inductor. The current is 2.5 A rms when the circuit is connected to a 120 V/60 Hz outlet.
    a. What is the inductance?
    b. What would be the current if this circuit were used in France, where the outlets are 220 V/50 Hz?

    I thought i could use the fundamental frequency equation

    f= 1/(2pi square root(LC)) but is the fundamental frequency 60 Hz?
    I got an L of 0.035 H
