question_answer

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: B

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.
