Ac Circuits

In an RLC (Resistor–Inductor–Capacitor) circuit, the Q-factor (Quality Factor) is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as: [ Q = fractextPeak energy storedtextAverage energy dissipated per radian ] At resonance, the Q-factor measures the sharpness or selectivity of the circuit's resonance. A higher Q-factor means a narrower and more selective resonance peak.
Explanation of Options:
(A) Dissipation factor: It is the inverse of Q-factor.
(B) Power factor: Relates to phase difference between voltage and current in AC.
(C) Q-factor: Correct. Measures energy stored vs energy lost per cycle.
(D) Impedance factor: Not a standard term used in this context.
