Which of the following is an accurate statement? A. Step-up voltage transformers have fewer turns in the primary that in the secondary winding. B. aC generators produce current that's 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 collage to a higher voltage D. DC generators produce current with a voltage that changes from positive to negative
