There is a step-down transformer that has 7500 turns in the
primary connected to a 13.2 KVolt distribution line, which in turn
feeds a factory that requires a voltage of 440 V with a total
current intensity of 70 Amps. Calculate:
a).- The number of turns in the secondary
b).- The current intensity in the primary
c).- The power of the transformer
