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