The secondary winding of a transformer has a terminal voltage
of vsec (t) = 234 sin (377t) V. The turns ratio of the transformer
(N1/N2) is 72:201. If the secondary current of the transformer
isec (t) = 12 sin(377t + [25°]), (a) What is the RMS value of the
primary current of this transformer? (b) What are its voltage reg-
ulation and (c) efficiency? The impedances of this transformer
referred to the primary side are Rsc = 0.222, Xsc = 0.759 and
Rc = 30022, Xm = 7022.
N.B. To compute the regulation, neglect the excitation current of
the transformer, io = ic+im.
