Which of the following combinations should be selected for better tuning of an L–C–R circuit used for communication?
R = 25 Ω, L = 1.5 H, C = 45 μF
R = 20 Ω, L = 1.5 H, C = 35 μF
R = 25 Ω, L = 2.5 H, C = 45 μF
R = 15 Ω, L = 3.5 H, C = 30 μF
Explanation:
Option with highest quality factor sould be chosen as most appropriate answer.
$Q = \dfrac{1}{R}\sqrt{\dfrac{L}{C}}$
