Extracted text: A three phase balanced load is connected across 220 V three phase source. A wattmeter reads 600 watts when its current coil is connected in line a and potential coil across line a and b. Next the voltage coil is connected between lines b and c, but the current coil remains at line a. The wattmeter again reads 600 watts. Calculate the load power factor.
