A transformer is created with 60 coils in its primary coil and 10 in its secondary coil. a)Is it a step-up or step-down transformer?

b)If are put into the primary coil, what voltage is induced in the secondary coil?

Example 2 Consider a transformer with 1200 turns in its primary coil and with a supply voltage of 22 kV. a)If it is designed to supply a voltage of 120 V for your house, how many turns will it need?

b)Is it a step-up or step-down transformer?
