A series RLC circuit resonates at 3 MHz and has 3-dB bandwidth of 10 kHz. The Q of the circuit at resonance
- A. 30
- B. 300/$\sqrt{2}$
- C. 300
- D. 300*$\sqrt{2}$
Answer: C. 300
Explanation: The quality factor (Q) of a resonant circuit is defined as the ratio of resonant frequency to the bandwidth. Q = f_r / B.W. = (3 * 10^6) / (10 * 10^3) = 300.
