Question:

Which of the following combinations should be used for better tuning of an LCR circuit used for communication ?

Options:

R = 25 Ω, L = 1.5 H, C = 35 μF

R = 25 Ω, L = 2.0 H, C = 45 μF

R = 15 Ω, L = 3.5 H, C = 30 μF

R = 15 Ω, L = 1.0 H, C = 40 μF

Correct Answer:

R = 15 Ω, L = 3.5 H, C = 30 μF

Explanation:

For tuning of a LCR Circuit, R should be low, L should be high and C should be low, Hence option 3 should be correct.
