Finding the charge on a capacitor

  1. Sep 30, 2012 #1
    1. The problem statement, all variables and given/known data
    http://screencast.com/t/B4865iOOLzX
    What is the charge on the 32 μF centered-
    upper capacitor?
    Answer in units of μC


    2. Relevant equations
    Q = CV
    1/c = 1/c1 + 1/c2......



    3. The attempt at a solution
    I found the charge across the entire thing and then divided that by 2, since the charge should be the same on all the plates. But that was wrong.

    What's the potential difference between nodes c and d?

    What do you know about the charge distribution on capacitors connected in series?
