    A bit of help with a capacitor problem

    1.35 x 10-3 J would imply a PD of .015 using formula E=(CV^2)/2, so V = .015. Using the formula C = Q/V, gives the charge on c3 to be .18C

    C2 in the answer. The questions asks for the change in the charge of C2.

    Sorry, I apologize, I mean't C2. C3 is what is given at the start.

    A bit of help with a capacitor problem

    1. The problem: In the capacitor circuit shown below C1 = 4␣F, C2 = 12␣F, C3 = 12␣F, and C4 = 3␣F. The switch (S) between A and B is closed and the energy stored in C3 is 1.35x10-3 J. If the switch is now opened calculate the change in the charge on C2. Assume the potential difference between C...
