A 360-V. 45-kVA, 0.8-PF-leading, Y-connected, 60-Hz synchronous motor has a synchronous reactance of 2.5 Q and an armature resistance of 0.4 Q. Assume that the Internal generated voltage EA (line-to-neutral

voltage) is equal to 1802-17.5 V, and the motor is supplying a load with a mechanical power of 12.5 kw. 1. Find the armature current (in A)
