The peak energy stored in an RLC circuit divided by the average energy dissipated in the circuit per radian at resonance is called:
Updated On: Jan 14, 2026
- Dissipation factor
- Power factor
- Q-factor
- Impedance factor
Show Solution
The Correct Option is C
Solution and Explanation
In an RLC circuit, the Q-factor (Quality Factor) quantifies the underdamping of an oscillator or resonator. It is calculated as:[Q = fractextPeak energy storedtextAverage energy dissipated per radian]At resonance, the Q-factor indicates the sharpness and selectivity of the circuit. A higher Q-factor results in a narrower and more precise resonance peak.
Options Analysis:
(A) Dissipation factor: This is the reciprocal of the Q-factor.
(B) Power factor: Pertains to the phase difference between voltage and current in AC circuits.
(C) Q-factor: Correct. It represents the ratio of energy stored to energy lost per cycle.
(D) Impedance factor: This term is not standard in this context.
