The factor of an ac circuit lies between:
The \( Q \) factor of an ac circuit lies between:
- A. 0 and 1
- B. - 1 and 1
- C. -1 and 0
- D. none of these
Step-by-step solution
The Q factor (quality factor) in an AC circuit is a positive dimensionless parameter that indicates the sharpness of resonance. It is defined as the ratio of energy stored to energy dissipated per cycle. Q can take any positive value, often exceeding 1 in high-Q circuits, and cannot be negative. Therefore, it is not restricted to intervals like 0–1 or –1 to 1.
