A linear transformer couples a load consisting
of a 360 2 resistor in series with a 0.25 H
inductor to a sinusoidal voltage source, as
shown. The voltage source has an internal
impedance of 184 + j0 N and a maximum volt-
age of 245.20 V, and it is operating at 800 rad/s.
The transformer parameters are R1 = 100 2,
= 0.5 H, R2 = 40 1, L2
k = 0.4. Calculate (a) the reflected impedance;
(b) the primary current; and (c) the secondary
current.
