## Homework Statement

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. (C

_{1}is charged.)

Then, switch A opens, and B closes.

V

_{i}=5v

C

_{1}=4.6x10^-6F

C

_{2}=2.3x10^-6F

## Homework Equations

Q = VC

## The Attempt at a Solution

Okay, so the first part is easy. Charge on the the first capacitor Q = VC, V=5v, Q

_{1i}= 2.3X10^-5 C

Now, the second part. Is charge conserved? So that

Q

_{1i}=Q

_{1f}+Q

_{2f}

Expanding that with Q=VC,

C

_{1}V

_{1i}= C

_{1}V

_{1f}+ C

_{2}V

_{2f}

Can we say that V

_{1f}= V

_{2f}? So V

_{f}would be 3.35v? Then charges could be found on each capacitor... Is this the correct way to go about this?
