36. The power flowing in a three-phase, three-wire balanced load system is measured by the two- wattmeter method. The reading on wattmeter A is 5 kW and on wattmeter B is -1 kW. If the voltage of the circuit is 440 V, 60 Hz, what is the value of the capacitance that must be introduced into each phase to cause the whole power measured to appear on wattmeter A? A. 74:64 µF B. 47.46 µF C. 64.47 µF D. 42.44 µF
