Question

Answer saved A series R-L-C circuit has R=10 Ω, L=0.5H and C=10μF. Calculate the frequency for maximum current flow in this circuit if it is connected to a source 100v.
Options
A 50Hz
B 60Hz
C 70Hz
D 71Hz
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

f = 1/(2π√(LC)) = 1/(2π√(0.5 × 10×10⁻⁶)) = 1/(2π√(5×10⁻⁶)) ≈ 71.2 Hz.

Hint

Resonant frequency f = 1/(2π√(LC)).
