In an ideal parallel \[LC\] circuit, the capacitor is charged by connecting it to a \[DC\,\] source which is then disconnected. The current in the circuit:

A)  becomes zero instantaneously

B)  grows monotonically

C)  decays monotonically

D)   oscillates instantaneously

Correct Answer: D

Solution :

When a charged capacitor is discharged through an inductor of negligble ohmic resistance, electrical oscillations takes place in the circuit. These are called \[L-C\] oscillations.
