An LRC circuit consists of a 15.0 μF
capacitor, a resistor, and an inductor connected in series across
an AC power source of variable frequency having a voltage amplitude
of 20.0 V. You observe that when the power source frequency is
adjusted to 44.5 Hz, the rms current through the circuit has its
maximum value of 65.0 mA. What will be the rms current if you
change the frequency of the power source to 60.0 Hz?

Homework Answers
given delta Vrms = 20.0 V; C = 15.0*10-6F
If, Irms (44.5Hz) = 65.0mA
then,
Irms (60.0Hz) = 87.64mA
