1. The problem statement, all variables and given/known data http://img141.imageshack.us/img141/6173/capcircuitji2.jpg [Broken] Basicly, I have to get charges and voltages as these switches are opened and closed on this capacitor circuit. First, Switch A closed, B open. (C1 is charged.) Then, switch A opens, and B closes. Vi=5v C1=4.6x10^-6F C2=2.3x10^-6F 2. Relevant equations Q = VC 3. The attempt at a solution Okay, so the first part is easy. Charge on the the first capacitor Q = VC, V=5v, Q1i= 2.3X10^-5 C Now, the second part. Is charge conserved? So that Q1i=Q1f+Q2f Expanding that with Q=VC, C1V1i = C1V1f + C2V2f Can we say that V1f = V2f? So Vf would be 3.35v? Then charges could be found on each capacitor... Is this the correct way to go about this?
