Q. If each of the values of inductance, capacitance and resistance of a series LCR circuit are doubled, the Q-factor of the circuit would
(A) reduce by a factor โ2
(B) reduce by a factor 2
(C) increase by a factor โ2
(D) increase by a factor 2
Ans: reduce by a factor 2
Sol:
In a series LCR circuit, Quality factor is given by
Given that each value of inductance capacitance and resistance are double.
Hence, Q – factor of the circuit will reduce by a factor of 2.
