Answer Posted / n k singh
As we know transformer is a static device and as per
Faradays law of electromagnetic induction the voltage in
the seconary will be induced if flux produced by primary is
changing with time. If primary is fed with DC then there is
no d/dt(of flux),so no emf will be induced in secondary.
