NEET Physics Resonance MCQ Question
Which of the following statements about resonance in AC circuits is correct?
Resonance occurs when the circuit has both inductance and capacitance, resulting in maximum current amplitude.
Resonance can occur in RC or RL circuits without the presence of a capacitor.
The sharpness of resonance increases with a larger bandwidth of frequencies at which resonance occurs.
The quality factor decreases when the resistance in the circuit is large.
Correct Answer
Detailed Explanation
Resonance in an AC circuit occurs when both inductors and capacitors are present, allowing the voltages across them to cancel, resulting in maximum current amplitude. This is highlighted in the context that resonance is only exhibited by circuits with both L and C.
