NEET Physics Resonance MCQ Question

Type: MCQ-numerical-Medium-Class 12

In a series RLC circuit, the resonance frequency ω0\omega_0 is given by ω0=1LC\omega_0 = \frac{1}{\sqrt{LC}}. If the inductance LL is doubled and the capacitance CC is halved, what happens to the resonance frequency?

A

It doubles.

B

It remains the same.

C

It halves.

D

It quadruples.

Correct Answer

Option B

Detailed Explanation

When the inductance LL is doubled and the capacitance CC is halved, the product LCLC remains unchanged. Hence, the resonance frequency ω0\omega_0 remains the same as ω0=1LC\omega_0 = \frac{1}{\sqrt{LC}}.
