Question

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-up voltage transformers have a lower number of turns in the primary than in the secondary winding. D. 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 1

The answer is C because of the following statements:

A) WRONG because DC Generators produce current with voltage that does not change over time

B) WRONG because AC Generators produce current that is sinusoidal but not pulsating

D) WRONG because step-down voltage transformers have a higher number of turns in the primary than in the secondary winding so they change from higher incoming voltage to a lower voltage.

B) CORRECT because step-up voltage transformers really have a lower number of turns in the primary than in the secondary winding so they change from lower incoming voltage to a higher voltage that is why is called step-UP

Step-by-step explanation:

Answer 2

I am pretty sure that the following option which contains an accurate statement is the third one represented above :C. Step-up voltage transformers have a lower number of turns in the primary than in the secondary winding. This one looks the most suitable and the others just make no sense. Do hope it will help you.
