Question

A series R-L-C circuit has R = 10 ohms, L = 0.5 H and C = 10 uF. Calculate the frequency for MAXIMUM current flow if connected to a 100 V source.
Options
A 50 Hz
B 60 Hz
C 70 Hz
D 71 Hz
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Max current at resonance: f=1/(2pisqrt(LC))=71.2 Hz.

Hint

Max current at resonance: f=1/(2*pi*sqrt(LC))=71.2 Hz.
