    Capacitor Circuit (Capacitor as source)

    Right, thanks. So, with that voltage, charge on each cap (Q=VC) is 3.35v * C1 and then 3.35v * C2 I get Q1f=1.55x10^-5 C and Q2f=7.6x10^-6 C However, when I run conservation of energy, U=.5QV (Ui = U1f + U2f) it doesn't work... EDIT: Well, more simply put: Is it voltage or charge that is...

    You mention a large effective capacitance..As in combining the two as one effective capacitor in parallel (C1 + C2)? Using Q = VC , taking the original Q1i and using (C1 + C2) I get the same 3.35v as I got before.

    Maybe this should be moved to the Introductory Physics help forum?
