What is Skin effect of the cable?

Answer Posted / vaibhav kumar pathak(bbdnitm l

The skin effect is the tendency of an alternating electric
current (AC) to distribute itself within a conductor so
that the current density near the surface of the conductor
is greater than that at its core.the outer strand flux
links external surface of the
cable,while internal mutual flux links both external &
internal surface of the cable thereby increasing the
inductance of the innner core of the cable which leads to
hindrance in flow of current in internal section of the
cable & hence concentration of current is higher on outer
surface called skin effect
