A transformer is designed to step down line voltage of 110 V to 22 V. The primary coil has 400 turns of wire.
a. How many turns of wire should there be on the secondary coil?
b. If the current in the primary coil is 5 A, what is maximum possible current in the secondary coil?
c. If the transformer gets warm during operation, will the current in the secondary coil equal the value computed in part b? Explain
