Capacitor Network (Please help!)
In the circuit below, consisting of a battery and several capacitors, some quantities are known and some are not. The capacitors were completely uncharged before the battery was attached and we are considering the static situation.
Circuit: http://img690.imageshack.us/i/showmepl.gif/
Q1= 8.5 × 10^-6 C
C1= 7.6 × 10^-6 F
C2= 2 × 10^-6 F
Energy stored on C2 is W2= 4.2 × 10^ -6 J
What is the charge Q3 on capacitor C3 ?
I've figured out that V1 = 1.12, V2 and V3 = 2.05...but I have no idea how to find Q3 because we don't know C3
