Question:
Which of the following combinations should be selected for better tuning of an LCR circuit used for communication?
(a) R = 20 Ω, L = 1.5 H, C = 35µF.
(b) R = 25 Ω, L = 2.5 H, C = 45µF.
(c) R = 15 Ω, L = 3.5 H, C = 30µF.
(d) R = 25 Ω, L = 1.5 H, C = 45µF.
Solution:
(c) R = 15 Ω, L = 3.5 H, C = 30µF.
