ANSWER:Nothing will happen.But fuse will blown off.
EXPLANATION: While applying DC voltage to the
transformer,there is no induced EMF in the primary &
secondary wdg.(except during switching period, both ON&
OFF).so,the transformer will draw high current from the
supply which detoriate the winding insulation & cause
transformer to burn.But actually this will not
happen .Becoz,the fuse will sacrifice itself to protect
transformer from high current.
