Answer Posted / wareagle
Skin effect is the tendency of an alternating electric
current (AC) to become distributed within a conductor such
that the current density is largest near the surface of the
conductor, and decreases with greater depths in the
conductor. The electric current flows mainly at the "skin"
of the conductor, between the outer surface and a level
called the skin depth. The skin effect causes the effective
resistance of the conductor to increase at higher
frequencies where the skin depth is smaller, thus reducing
the effective cross-section of the conductor. The skin
effect is due to opposing eddy currents induced by the
changing magnetic field resulting from the alternating
current
