Why Skin Effect Occurs in Transmission Lines?

Why Skin Effect Occurs in Transmission Lines?

The distribution of current throughout cross section of  a conductor is uniform only when DC is passing through it. When Alternating Current(AC) is passing through a conductor, the current is non uniformly distributed over the cross section in a manner that the
