Answer / muhammad abbas

When the no of turns in secondary are less than the no of
turns in primary the voltage induced in secondary is less
than the voltage applied at primary,so step down process is
done.

Answer / venkatesh

primary turns is more than the secondary turns in transformer.

Answer / ambreesh biradar(abb)

by using by step down transformer.in transformer voltage is
directly propotional to the number of
turns.vs/vp=ns/np=ip/is

In alternator generally we give DC voltage to field of alternator but field (excitor)produce Ac & converts into DC by rotating rectifier(RR ) then fed to rotor .my question is why we cannot give dc voltage directly to rotor instead of Excitor & RR ?
