An electric motor is monitored with an ammeter, voltmeter, and wattmeter, which indicate 5.2A, 120V, and 480W respectively. Assume 60Hz.
A) Draw the phasor diagram of the voltage and current,assuming the voltage at zero phase and lagging current.
B) What is the reactive power to the motor, including theunits.
C) To improve the power factor of the motor, a capacitor ishung directly across the motor terminals. What values ofcapacitance will give unity power factor?
