Question

The quality factor is the product of 2π and the ratio of ______ to _________

(a) maximum energy stored, energy dissipated per cycle

(b) energy dissipated per cycle, maximum energy stored

(c) maximum energy stored per cycle, energy dissipated

(d) energy dissipated, maximum energy stored per cycle

I had been asked this question during an online exam.

I'd like to ask this question from Resonant Frequency for a Tank Circuit topic in chapter Resonance & Magnetically Coupled Circuit of Network Theory

Answer 1

Correct option is (a) maximum energy stored, energy dissipated per cycle

The explanation is: At low frequencies XL is very small and XC is very large so the total impedance is essentially inductive. The quality factor is the product of 2π and the ratio of maximum energy stored to energy dissipated per cycle.
