engineering recuitment GATE EE 2023-24 Test Series Electrical and Electronics Measurements Measurement of Power Measurement of AC Power
The current coil of a wattmeter is connected in series with an ammeter and inductive load. The voltmeter and voltage coil are connected in series across a 50 Hz supply. The ammeter reading is 5 A and voltmeter and wattmeter readings are 120 V and 15 W respectively. The inductance of voltage circuit is 2 mH and resistance 500 Ω. If voltage drop across ammeter and current coil are neglected, then what is the power factor of load upto four decimal places
