Which of the following combinations

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.
