How much charge passes through a part of a circuit?

  1. Apr 18, 2006 #1
    Suppose the the two capacitors are charged fully before the switch is closed, how much charge will pass through the switch when we close it?

    I've been trying for a long time but I'm lost. All help I could get would be appreciated.

    I would start by considering that the two capacitors really only form one without the switch closed. Can you determine the initial charge?
