A 7200-240V, 60 Hz transformer is connected for step up operation, and a 144<46degrees -Ω load is connected to the secondary. Assume the transformer is ideal and the input voltage is 220 V at 60Hz. Determine (a)secondary voltage; (b)secondary current; (c)primary current; (d)input impedance at primary terminals of transformer; (e)active, reactive, and apparent power input to transformer.
