Answer Posted / jaya bharath reddy
generally, transformer o/p is come by mutual induction i.e,
flux produced in primary coil causes the flow of current in
secondary coil. mainly, flux is produced by time varying
fields i.e, ac signal since the ac signal is time variant
but dc signal is time invariant signal it is constant all
the values of time . so, flux is not produced in the
primary coil consequently no flow of current in secondary
coil.
