NEET Physics RLC Circuits MCQ Question
Consider a series RLC circuit where a resistor, an inductor, and a capacitor are connected in series with an AC source. In the context of resonance, what happens to the bandwidth of the circuit as the quality factor Q increases?
The bandwidth decreases.
The bandwidth increases.
The bandwidth remains unchanged.
The bandwidth oscillates randomly.
Correct Answer
Detailed Explanation
In a series RLC circuit, a higher quality factor Q corresponds to a sharper resonance, meaning a smaller bandwidth. This is because a larger Q indicates less energy dissipation per cycle relative to the stored energy, thereby decreasing the range of frequencies over which the circuit is close to resonance.
