SKIN EFFECT

Skin effect is the phenomenon where the apparent resistance of a wire increases as the frequency increases. At higher frequencies a thin surface layer of the wire carries all the current. Therefore the effective wire size is smaller. To avoid problems with increased resistance at high frequencies, large wires are often replaced with bundles of many small wires. Although the cross sections of the large and multiple-small wires are the same, the small wire bundle has a much larger surface area and therefore a greater current carrying capacity.
