A 7200-240-V, 60-Hz transformer is connected for step-up operation, and a 144/46°-2 load is connected to the secondary. Assume the transformer is ideal and the input voltage is 220 V at 60 Hz. Determine (a) secondary volt- age; (b) secondary current; (c) primary current; (d) input impedance at pri- mary terminals of transformer; (e) active, reactive, and apparent power input to the transformer. 2-9/8
