why should a transformer be never connected to dc supply..

Answer / bapan

If Dc supply is given to atransformer there will be no change in the flux with time.so,there is no emf induced in the primary and secondary winding and hence transformer action will not take place.

Answer / r. p. siroih

The transformer works on the basis of to transfer the energy (votage) to stepping down or up in alernative mode. In the DC power the current flow in streight line, so transformer can not transfer the voltage .
