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 5kW and on wattmeter B is -1kW. If the voltage of the circuit is 440V, 60Hz, what is the value of the capacitor that must be introduced into each other phase to cause the whole power measured to appear on wattmeter A? Assume the capacitor to be Y-connected.
