In the circuit shown, each capacitor initially has a charge of magnitude 3.50 nC on its plates. The capacitances of C1, C2, and C3 are 15.8 pF, 19.4 pF, and 9.8 pF respectively. The resistor is 26.0 ?. After the switch S is closed, what will be the current in the circuit at the instant that the capacitors have lost 65.0% of their initial stored energy? At this energy, what is the voltage drop across C2?
