a) The AC motor M shown in figure 18 has 2300 Volts, balanced three-phase voltage impressed at its terminals and takes 120 kVA at 0.6 leading power factor. Calculate the line current, total power, and total power factor using Vmotor as the reference vector. b) If the motor in problem 1 is removed from the circuit and a balanced three-phase line voltage of 2300 Volts is impressed each at lines A, B, and C, how many volts will appear between lines at the end of the motor?
