Question

Sinusoidal voltage applied to series RLC: L=10mH, C=100nF, R=20Ω. Quality factor Q?
Options
A 1.58
B 15.8
Correct Answer
C 158
D 18.5
Correct Answer

Option B is the correct answer.

Detailed Explanation

ω₀ = 1/√(LC) = 1/√(0.01 × 1e-7) = 1/√(1e-9) = 31623 rad/s. Q = ω₀L/R = (31623 × 0.01)/20 = 316.23/20 = 15.8. Option B.

Hint

Q = (1/R)√(L/C).
