Q. In L – C – R circuit if resistance increases, quality factor
A) Increases finitely
B) Decreases finitely
C) Remains constant
D) None of the above
Explanation
(b) The Q- factor of series resonant circuit is given by
$Q = \frac{\omega_{r}^{2}L}{R}$
It is evident from the relation that as R is increased, Q – factor of the circuit is decreased.
