How does the quality factor (Q) relate to resonance in an LC circuit?.
- A.It indicates the circuit's resistance
- B.It measures the sharpness of the resonance peak
- C.It determines the frequency of the circuit
- D.It has no effect on resonance
Model answer
What a good answer should say
- It measures the sharpness of the resonance peak
Explanation
Why this works
The quality factor (Q) of an LC circuit quantifies the sharpness of the resonance peak. A higher Q indicates a narrower and sharper peak, signifying lower energy loss and higher efficiency at resonance.
