why dc power can not be used in transformer?
Answer Posted / ilaya
dc power can't used in transformer. because dc power is
unidirectional.basicaly emf induced in two way,
1).condctor is stationary and flux is rotating.
2).flux is stationary and condctor is rotating.
so dc supply give to transformer,it produce stationary
magnatic field and also conductor is stationary.so no emf
induced in secondary.if dc supply maintain to the
transformer heat is produced(transformer windings are low
resistance).finaly windings are burn.so transformer is not
working in dc power.
(incase ac supply flux is rotating(rotating magnatic field)
and conductor is stationary.so emf is produce in secondary
winding)
