Topic: Network Theory
The Q factor of a RLC circuit is 5 at its resonance frequency of 1 kHz. Find the bandwidth of the circuit.
- A. 100 Hz
- B. 200 Hz
- C. 400 Hz
- D. 50 Hz
Answer: B. 200 Hz
Explanation: $Q \text{ factor} = 5$
$f_R = 1 \text{ kHz}$
$\text{Bandwidth} = \frac{f_R}{Q} = \frac{1000}{5} = 200 \text{ Hz}$.
