Why DC current is not used in transformer?
Answer Posted / minal verma
In a transformer, when ac current flows then due to its
frequency an emf is induced in it due to electromagnetic
induction.
But when a DC current flows through the transformer, then
no emf is induced in it because there is no frequency in dc.
Thus dc current is not used in transformer.
