Resonance Curve and Q-factor:
Resonance curve is a plot of impedance magnitude or current versus frequency for a resonant circuit. The shape of the resonance curve depends upon the Q-factor of the circuit.
Q-factor:
- Q-factor (Quality factor) is a measure of the selectivity of a resonant circuit. It is defined as the ratio of energy stored to energy dissipated in one cycle of oscillation.
- Higher the Q-factor, sharper the resonance curve. A high Q-factor means a narrow bandwidth and a tall, narrow peak in the resonance curve.
- Lower Q-factor results in a broader resonance curve with a lower peak.
Therefore, the shape of the resonance curve depends primarily on the Q-factor of the circuit.
In summary, the Q-factor plays a crucial role in determining the shape of the resonance curve. It is a measure of the selectivity of the circuit and affects how sharply or broadly the curve peaks at resonance. The higher the Q-factor, the sharper the resonance curve, while a lower Q-factor results in a broader curve. Thus, the Q-factor is the key factor influencing the shape of the resonance curve.

The shape of the resonance curve in a resonant circuit depends on the Q-factor (Quality Factor) of the circuit. The Q-factor is a measure of the sharpness or selectivity of the resonance.
A higher Q-factor indicates a narrower resonance curve with a sharper peak, while a lower Q-factor results in a wider resonance curve with a broader peak. The Q-factor is influenced by various factors such as the resistance, inductance, and capacitance of the circuit components.
The Q-factor determines the bandwidth of the resonant circuit and its ability to discriminate between different frequencies. A higher Q-factor indicates a circuit with a higher level of resonance and a more selective response to a specific frequency.
The shape of the resonance curve depends on the Q factor because of the equation:
BW = fr/Q.
BW = fr/Q.
Therefore, the shape of the resonance curve depends on the Q-factor, making option A the correct answer.
