1. The problem statement, all variables and given/known data http://img512.imageshack.us/img512/6864/59797183jd5.png [Broken] (capacitance in micro farads). Initially the switch is at the left position and capacitors C_2 and C_3 are uncharged. Then the switch is flipped to the right position. Afterward, what are the chard on and the potential difference across each capacitor? 3. The attempt at a solution First I turned C_2 and C_3 into a capacitor with equivalent capacitance 12 uF. Before the switch flip, C_1 is charged to 100V and has 1.5 mC of charge. I'm not sure what happens after the switch flips though. Does C_1 still affect the circuit? If not, then its charge and voltage won't change from before it flipped. And then the voltage and charge on C_2 and C_3 are completely unaffected by the presence of C_1?
