The primary winding of an ideal transformer with N1 100 and N2 250 is connected

The primary winding of an ideal transformer with N1 ¼

100 and N2 ¼ 250 is connected to a 480-V source. A load impedance of ZL ¼ 150 þ j200 V is connected across the secondary windings. Find the amplitudes of the primary and secondary currents.
