Question 1 POST_UTME_UI • 2017 • PHYSICS • objective

A 2-pole, 4-wire, star-connected alternator has a rated voltage of 400 V and a rated current of 50 A. If the alternator is operating at a frequency of 50 Hz, calculate the value of the synchronous impedance per phase.

Answer Options

Correct Answer A. \frac{400\angle0^\circ}{50\angle0^\circ} = 8\angle0^\circ\Omega
B. \frac{400\angle0^\circ}{50\angle0^\circ} = 8\angle90^\circ\Omega
C. \frac{400\angle0^\circ}{50\angle0^\circ} = 8\angle180^\circ\Omega
D. \frac{400\angle0^\circ}{50\angle0^\circ} = 8\angle270^\circ\Omega
Correct Answer
A
Correct Option:
\frac{400\angle0^\circ}{50\angle0^\circ} = 8\angle0^\circ\Omega
