Answer Posted / gaurav kr rai
in a conductor the resistance on the surface is lesser than the resistance in the core of the conductor because of the cross sectional area increased at surface as we know that resistance R is inversely proportional to cross sectional area.So when an A.C. current passes through the conductor mostly it travels on the surface of the conductor and this phenomena is known as skin effect.
