Very short physics question?

  1. Jul 4, 2013 #1
    1. The problem statement, all variables and given/known data

    What do a capacitor and a selenoid have in common?

    2. Relevant equations



    3. The attempt at a solution

    This looks like part of a good multi-choice question. Can you provide the 4 options to choose from?

    I would say what they don't have in common, they appear to do the opposite,
    Look how an inductor (solenoid) affects current/voltage and how a capacitor affects current/voltage, should be relatively straight forward.

    That's one thing you could look at anyway. Is that the full question?

    I think the question might have something to do with energy.
    Might want to read up on this for both devices.

    It does have something to do with energy.

    Hint: Resistors can't do it.
