NEET Physics Resonance MCQ Question
Type: MCQ-conceptual-Hard-Class 12
In a series RLC circuit at resonance, if the inductance is doubled and the capacitance is halved, what happens to the resonant frequency?
A
It remains unchanged.
B
It doubles.
C
It is halved.
D
It quadruples.
Correct Answer
Option A
Detailed Explanation
The resonant frequency is given by . If L is doubled and C is halved, the product LC remains the same, thus remains unchanged.
