Solution
Correct Answer:
Narrow sharp resonance
The Quality Factor (Q) describes the 'sharpness' of resonance in an RLC circuit. Q=Rω0L=ω0CR1=R1CL
- 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.
