Electricity and Magnetism Question (Related to circuits). Please Help.

  1. May 17, 2009 #1
    A 1.0 E -6 F capacitor has a charge of 10.0 micro C. It is connected to a 1.0 H inductor at t = 0. Compare the potential energy of the capacitor to the potential energy of the inductor at t = 10s. Which energy is greater?

    Welcome to PF.

    Connected how?

    And what are your thoughts on it?

    First of all thanks.

    My thoughts

    I know that potential energy is basically voltage across each component.
    Also, C = Q / (change in V) ; C is the capacitance, Q is the charge, and V is volts.
    solving for change in V and we get
    V = Q / C

    Am I going in the right direction?

    First of all I don't know how it's connected. Is the inductor in || to the capacitor? What is the circuit?

    That's all the problem says. Lets assume that it is in series then how would I approach the problem?

    If it is in series then I think it matters what the rest of the circuit would be.

    If it is in || then one is a short to the other isn't it?

    Isn't the decay constant pretty swift?
