A series RLC circuit has a resonance frequency of 1 kHz and a quality factor Q = 50. If R and L are doubled and C is kept same, the new Q of the circuit is?
(a) 25.52
(b) 35.35
(c) 45.45
(d) 20.02
The question was posed to me in a job interview.
My doubt stems from Problems of Series Resonance Involving Frequency Response of Series Resonant Circuit topic in division Resonance & Magnetically Coupled Circuit of Network Theory
