In a transformer , we know that the no-load current has two components , one magnetizing component I0sinphiand other one is the winding loss component i.e. I0cosphi..
if the magntizing current increases in the transformer what is the effect on the power factor??

How can the magnetising current increase without there also being a change in the resistive losses ?
