The secondary winding of a transformer has a terminal voltage of vs (t) = 282.8 sin 377t V . The turns ratio of the transformer is 50:200 (a = 0.25). If the secondary current of the transformer is (t) = 7.07 sin (377t - 36.87°) A , what is the primary current of this transformer? What are its voltage regulation and efficiency? The impedances of this transformer referred to the primary side are

Req = 0.05 W      RC = 75 W

X eq = 0.225 W   X M = 20 W
