Capacitor C1 has a capacitance of 1 x 10-6 F and capacitor C2 has capacitance 2 x 10-6 F. Initially the switch S is open and the charge on C1 is 3 x 10-6 C and the voltage difference between the upper and lower plate of C2 is 4 V. At time t = 0 the switch is closed.
a) For time t < 0 how much charge was on C2?
b) For time t > 0 how much charge will be on C2?
c) How much energy will be lost from the system when the switch is closed?
