Homework Help: Current Through an Oscillating LC Circuit

  1. Mar 18, 2005 #1
    An oscillating LC circuit consisting of a 7.5 nF capacitor and a 4.4 mH coil has a maximum volatage of 2.0 V. What is the maximum current through the circuit?

    I got 1.5x10^-8 C for the max. charge.

    [tex]\frac{1}{2}L I_m^2=\frac{1}{2}CU_m^2[/tex]

    Got it. Forgot about the ability to set those equal to each other in oscillation.

    Thanks!
