why dc power can not be used in transformer?
Answer Posted / kavitha
transformer is a static device.emf is induced only when
there is a rotating part.if we are giving dc supply flux
produced by dc supply also remains constant.hence there is
no emf will be induced in secondary.so when we giving ac
supply time vary flux will be produced.for this reason we
are giving only dc supply.
