2. The synchronous reactance for a round rotor synchronous generator is 1.0 and the armature resistance is negligible. Find the real power delivered by the generator when the terminal voltage is and the open-circuit voltage is(10%)

1. A 380 V, 20HP, 60 Hz four-pole Y-connected three phase induction motor has the following impedances in ohms per phase referred to the stator circuit: R1 =0.6 ohm, Xl = 1 ohm, R2=0.3 ohm, X2 =0.45 ohm, (magnetizing reactance) =25 ohm. The total rotational losses are 1000W and are assumed to be constant. The core loss is neglected. For a rotor slip of 2 percent at the rated voltage and rated frequency, find the motor's stator current. (10%)
