A linear transformer couples a load consisting
of a 360 O 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 + /0 Cl and a maximum voltage of 245.20 V, and it is operating at 800 rad/s.
The transformer parameters are Ri = 100 fl,
Lt
= 0.5 H, R2 = 40 O, L2 = 0.125 H, and
k = 0.4. Calculate (a) the reflected impedance;
(b) the primary current; and (c) the secondary
current.
