A circuit contains a capacitor and inductance each with negligible resistance. The capacitor is initially charged and the charging battery is disconnected. At subsequent time, the charge on the capacitor will

A

increase exponentially

B

decrease exponentially

C

decrease linearly

D

remain constant

Text Solution

Verified by Experts

The correct Answer is:
D
When a charged capacitor is allowed to discharge through a resistance less inductor, electrical oscillations of constant amplitude are produced in the circuit. These are called L-C oscillations.
