Multiple Choice
A series circuit contains an 80-μF 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 potential across the capacitor is 30 V,what is the rate of change of the current?
A) 1000 A/s
B) 1500 A/s
C) 2000 A/s
D) 2500 A/s
E) 3000 A/s
