Homework Statement
http://img141.imageshack.us/img141/6173/capcircuitji2.jpg
Basically, 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^-6 F
C2=2.3x10^-6 F
Homework Equations
Q = VC
The Attempt at a Solution
Okay, so the first part is easy. Charge on the the first capacitor Q = VC, [(5)*(4.6x10^-6)] = 2.3X10^-5 C = Q1i
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?
Or, Is the voltage the same, 5v across all the capacitors? (Being in parallel.)
