What is Skin effect of the cable?

Answer Posted / c siva ( kec )

The Concentration of current flow (AC) will be more in the
outer surface of the conductor and as it reaches center of
the conductor the flow will be less i.e. movement of free
electrons will be more in the outer surface. That is why we
use multistands in conductors.

( Skin effect will not be there in DC power supply)
