    Why we do not give DC supply in transformer means DC current is a direct current, so alternating flux is not produced, because input supply and flux will be same, so emf will not produced and same tim...

    Current=voltage/impedance, When DC is applied then Z=R =>I= V/R and R is low for transformer, so I increases very high, so heating as current is not allowed to flow further and hence intuitively you c...
