A 100 kVA, 415 generates rated open of 15 A. The short star-connected V (line), synchronous machine circuit voltage of 415 V at a field current circuit circuit armature current at a field current of 10 A is equal to the rated armature current. The per unit saturated synchronous reactance is (A) 1.731 (C) 0.666 (B) 1.5 (D) 0.577
