In india the geration and transmission voltage is AC..
(1.DC generation also available but we could not going to
generate as much as our require because it has some
limitation for commutator & Brush in DC generator and
also transmission of DC supply is so complicated in

2.Domestic items all are (Manufactured)working in AC)
and also in india transmission voltage for domestic
purpose is AC voltage.so we r using AC supply in domestic
purpose.
