MCQ

In an ideal parallel $LC$ circuit, the capacitor is charged by connecting it to a $D.C.$ source which is then disconnected. The current in the circuit.

A
Becomes zero instantaneously
B
Grows monotonically
C
Decays monotonically
✓
Oscillates instantaneously

✓

Answer

Correct option: D.

Oscillates instantaneously

In an $LC$ circuit current oscillates between, maximum and minimum value. So, $LC$ circuit needs oscillations $($electrical$)$. It occurs due to discharging and charging of capacitor and magnetisation and demagnetisation of inductor
