A 10 KVA, 200 V single-phase alternator with a 5 A disturbance produces a voltage of 200 V in the absence of load. When the terminals of the armature are short-circuited, the rated armature current flows with a disturbance of 2A. What would be its per unit impedance with a base voltage of 200 V and a base kVA of 20?
