The quality factor in case of parallel resonant circuit is?

(a) C

(b) ωrRC

(c) ωrC

(d) 1/ωrRC

This question was addressed to me in examination.

The doubt is from Resonant Frequency for a Tank Circuit in division Resonance & Magnetically Coupled Circuit of Network Theory

Best answer
Right choice is (d) 1/ωrRC

The best I can explain: The quality factor in case of parallel resonant circuit is Q = 1/ωrRC. The impedance of parallel resonant circuit is maximum at the resonant frequency and decreases at lower and higher frequencies.
