Question

Which of the following is an accurate statement?

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

Answer 1

B. 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.

Answer 2

the answer is c step-up voltage have lower number of turns
