no there is no dc transformer because if we use DC there is
always a positve cycle .so at the time of switch ON,from 0
to + ve,we will get little o/p voltage.Since the resistance
of primary winding is quite low therefore a heavy current
will flow through primary winding ,which may burn out the
primary winding.
