Question

A transformer is to be used to step down voltage from an alternating current source from 220V to 110V. If the primary has 120 turns, then the number of turns in the secondary is.

Answer 1

The number of turns on the secondary would be 60.

Step-by-step explanation:

The voltage is to be cut in half. The ratio between the primary and secondary, for a step-down transformer, would then be 2:1.

120 turns / 2 = 60 turns
