Calculate the resulting charge on each capacitor

  1. Sep 29, 2008 #1
    Capacitors C1 = 6.35 µF and C2 = 2.00 µF are charged as a parallel combination across a 250 V battery. The capacitors are disconnected from the battery and from each other. They are then connected positive plate to negative plate and negative plate to positive plate. Calculate the resulting charge on each capacitor.
    q'1 = µC
    q'2 = µC

    Can someone please help me with this, I don't know what to do.

    Re: Capacitors

    First you have to find the charge on each capacitor after it has been charged. Then note from the statement of the problem whether the new connection yields a series or parallel connection.

    From here, note that if the caps are in series, the resulting charge (if you let the circuit stabilise) on each capacitor will be the same. If they are in parallel, then their final potential differences will be the same. From these 2 conditions you can calculate the final charge on each cap.
