what is skin effect? why is it absentin dc system

Answer Posted / karthik

The current flow in a multi-stranded conductor tends to flow
more on the outer surface than in the inner surface.This is
due to the reason that the flux linkages in the multi-strand
conductors cancel each other in the inner strands than on
the outer strands.Due to this the current flow varies.Also
no alternating fluxes are produced in DC current flow.So the
skin effect is not defined for it.
