Q. Q-factor can be increased by having a coil of
A) Large inductance, small ohmic resistance
B) Large inductance, large ohmic resistance
C) Small inductance, large ohmic resistance
D) Small inductance, small ohmic resistance
Explanation
(a) $Q$ factor is given by $\frac{1}{R}\sqrt{\frac{L}{C}}$
So, for large quality factor the inductance should be large and resistance and capacitance must be small
