A transformer consists of 330 primary turns and 1340 secondary turns. When the input voltage at the power generation station is 15000 V:
i) Determine the output voltage?
ii) When the copper wire transmitting the electricity consists of a diameter of 4 cm and is 1 mile long, find out the current in the wire?
iii) When the voltage is stepped down to 120 V to use in your home and the transformer outside your home consists of 550 turns in the secondary coil, determine how many turns are on the primary coil?
