The effective resistance of a 2200V, 50Hz, 440 KVA, 1 -phase alternator is 0.5 ohm. On short-circuit, a field current of 40 A gives the full load current of 200 A. The electromotive force on open circuits with the same field excitation is 1160 V. Then the synchronous impedance and reactance are _______ ohm and _______ ohm respectively.
