The generator supplies a star-connected balanced load of (10 + j6)Ohm per phase through a line, the impedance of which is (0.4 + j0.08)Ohm per phase. The load neutral is directly grounded and the generator neutral is grounded via a 15Ohm. resistor. Use Millman's theorem to determine the current in the 15Ohm neutral resistor.
