Answer 2

Answer:

Thus we see that, when the power factor of load is unity then both the wattmeter reads the same value. Case2: When power factor of load is 0.5 lagging. Thus we see that, when power factor of load is 0.5 lagging then power is only measured by first wattmeter and reading of second wattmeter is ZERO
