Why DC current is not used in transformer?
Answer Posted / michael j.
In an a/c transformer, because of the alternating current
in the primary coil, a current is induced in the secondary
coil because the wires in the secondary cut acroos the
magnetic field lines of the primary coil.(magnetic
inductance). a d/c current on the other hand does not have
a collapsing magnetic field because its current is
constant. therefore, no collapsing magnetic field means no
induced current.
