Unformatted text preview: a) If the transformer were ideal, what would be the magnitude of the current on the primary (480 V) side? (Answer: 10 Amps) b) What is the impedance of the load under the ideal assumption? c) Again, if the transformer is ideal, what would the impedance be as viewed from the primary side? (Answer: 38.4+j28.8 Ohms)....
