NEET Physics Resonance MCQ Question
In a series RLC circuit, if the resistance is decreased while keeping the inductance and capacitance constant, what will be the effect on the sharpness of resonance?
The resonance becomes sharper.
The resonance becomes less sharp.
The resonance frequency increases.
The resonance frequency decreases.
Correct Answer
Detailed Explanation
According to the NCERT context, a larger quality factor (Q), achieved by decreasing resistance (R), results in a sharper resonance. Therefore, decreasing the resistance sharpens the resonance.
