NEET Physics Resonance MCQ Question
Which of the following statements about resonance in AC circuits is correct?
Resonance occurs only in circuits that include both an inductor and a capacitor.
Resonance can occur in RL or RC circuits without an inductor.
At resonance, the impedance of the circuit is at its maximum.
The current at resonance is independent of the resistance in the circuit.
Correct Answer
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.
