The quality factor shows us.
Correct answer: C. The ratio of energy stored to energy dissipated per cycle
- A. Energy stored per cycle
- B. Energy dissipated per cycle
- C. The ratio of energy stored to energy dissipated per cycle
- D. Power loss
Explanation
The Quality Factor (Q) of a resonant circuit is a measure of its "quality" or sharpness of resonance. It is defined as 2π times the ratio of the maximum energy stored in the circuit to the energy dissipated per cycle.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
