NEET Physics Resonance MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about resonance in AC circuits is correct?
A
Resonance occurs only in circuits that include both an inductor and a capacitor.
B
Resonance can occur in RL or RC circuits without an inductor.
C
At resonance, the impedance of the circuit is at its maximum.
D
The current at resonance is independent of the resistance in the circuit.
Correct Answer
Option A
Detailed Explanation
Resonance in AC circuits requires both an inductor and a capacitor to cancel out their voltages, resulting in maximum current amplitude. This is stated in the context that resonance cannot happen in RL or RC circuits.
