Skin effect is the behavior of electron current flow to mostly be on the surface, or "skin", of the conductor. This is due to the fact that like charges repel one another, so the electrons migrate away from each other to the skin of the conductor. This effect is particularly noticable with high voltage circuits. The impact of skin effect is that the inner parts of the conductor are not really participating in supporting the current flow, so the conductor must be made larger than expected in order to carry the current flow. In fact, many high voltage transmission conductors have a light weight non-conductive core that is used for tensile strength rather than for current carrying capacity.

Skin effect is also related to the system frequency. At higher and higher frequencies, electrons tend to migrate even more to the outer surface of the conductor. In low frequency systems it is not so much a factor because it is negligible, unless high voltage such as in long distance power transmission systems in involved
