An RLC circuit is connected across a variable frequency, 110-volt source. When the frequency is varied, the maximum effective (rms) value of the current is 5.6 A and occurs at 45 Hz frequency. At this frequency, the voltage across the capacitor is 200.8 volts. Determine the power factor of the circuit at 60 Hz.
