quality factor hard

Question

High Q factor in resonant circuit implies:

RankGuru · Accepted Answer

The Quality Factor ($Q$) describes the 'sharpness' of resonance in an RLC circuit.
$Q = \frac{\omega_0 L}{R} = \frac{1}{\omega_0 CR} = \frac{1}{R}\sqrt{\frac{L}{C}}$
- **High Q**: Low resistance / damping. The peak current at resonance is very high, and the 'bandwidth' (the range of frequencies where current is significant) is very narrow.
- This makes the circuit highly selective, which is desirable for radio tuning.
