Transformer is a static device which is working on intromagnetic induction principal. Transformer only works in AC supply because for induction process, it is necessary to present change of flux. And in DC supply there will be no flux change phenomenon happen so induction process couldn't be happen. That's why transformer is used in AC supply.Modal content

Transformer is a static device which converts the level of voltage keeping frequency constant. .
Yes it works on AC only...
because transformer has 2 winding....primary and secondary. The emf induces in secondary winding due to change in flux linking ...this is possible only in AC...
while working with DC ,there is constant current...and flux follows the path of current...so there is no change in flux linking...
sso transformer can not work on dcModal content

transformer is a device that in used for increase and decrease the value of voltage without change in frequency.
transformer work only on ac supply because A transformer needs an alternating current that will create a changing magnetic field. A changing magnetic field also induces a changing voltage in a coil. This is the basis of how a transformer works: The primary coil is connected to an AC supply.Modal content
