Calculate the power factor and phase angle in a sinusoidal current-carrying circuit from the measurements of current, voltage and power. The reading of the current was 2.5 amps on a scale of 5 amps and the reading of the voltage of 200 volts on the scale of 250 volts and the capacity of 220 watts on the scale of 500 watts. The ammeter and voltmeter are guaranteed up to 1% +- of the highest scale reading as well as the wattmeter Calculate the percentage of accuracy of the measured readings
