LC Circuits: A series circuit contains an 80-?F capacitor, a 0.020-H inductor, and a switch. The resistance of the circuit is negligible. Initially, the switch is open, the capacitor voltage is 50 V, and the current in the inductor is zero. At time t = 0 s, the switch is closed. When the current in the circuit is 1.5 A, what is the charge on the capacitor?
A. 2000 µC
B. 2500 µC
C. 3000 µC
D. 3500 µC
E. 4000 µC
