Answer Posted / anil
there should be a relative motion to induce an emf i.e
either a rotating rotor field with dc or alternating supply
to the stationary core in case of transformer if we give
constant dc than there is a constant flux linking with the
secondary which will not produce any emf in secondary and
thus since there is no opposition to the primary emf and
the resistance of winding is very small this will lead to
high currents in primary and thus may lead to the burning
this is not in case of alternator since the rotor is
rotating
