NEET Physics Resonance MCQ Question
Which of the following statements about resonance in AC circuits is correct?
Resonance occurs only when both an inductor and a capacitor are present in the circuit.
Resonance can occur in a circuit with only a resistor and an inductor.
The quality factor Q decreases with increasing resistance in the circuit.
At resonance, the current amplitude is independent of the total source voltage.
Correct Answer
Detailed Explanation
Resonance in AC circuits requires both an inductor and a capacitor, as their voltages cancel each other, leading to maximum current amplitude, as stated in the NCERT context.
