Which of the following is an accurate statement?

A. DC Generators produce current with a voltage that changes from positive to negative.
B. AC Generators produce current that is pulsating, but always remains positive.
C. Step-down voltage transformers have a different number of turns in the primary than in the secondary winding, so they change the incoming voltage to a higher voltage.
D. Step-up voltage transformers have a lower number of turns in the primary than in the secondary winding

The correct option is D. Step-up voltage transformers have a lower number of turns in the primary than in the secondary winding is an accurate statement.

What's the difference between the primary and secondary windings in a step-up transformer?

The primary winding of a step-up transformer is built of thick insulated copper wire, whereas the secondary is made of thin insulated copper wire. In contrast, the secondary winding of a step-down transformer is constructed of thick insulated copper wire because the output current is higher.

Compared to the primary coil, the secondary coil of a step-up transformer has more turns. When comparing the applied and induced voltages across the primary and secondary coils, the secondary coil exhibits a higher voltage.
