The most important effect of skin effect on the impedance of a single wire is the increase of the wire's resistance, and consequent losses. The effective resistance due to a current confined near the surface of a large conductor (much thicker than δ ) can be solved as if the current flowed uniformly through a layer of thickness δ based on the ...
Examples of skin depth in copper wire at different frequencies At 60 Hz the skin depth of a copper wire is about 7.6 mm (0.30 inches). At 60,000 Hz (60 kHz) the skin depth of copper wire is about 0.25 mm (0.0098 inches). At 6,000,000 Hz (6 MHz) [5] the skin depth of copper wire is about 25 μm (0.00098 inches).
Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are designated by the number of zeros: No. 0, often written 1/0 and referred to as "one aught" wire

A wire is a flexible, round, bar of metal. Wires are commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number or cross-sectional area. Wires are used to bear mechanical loads, often in the form of wire rope.
The choice of metals in the conductor makes a difference, too: silver has a greater skin effect than copper; aluminum has less effect. Skin effect is a significant problem at radio frequencies or over long distances such as miles and kilometers worth of high-tension electrical transmission lines, but not at audio frequencies carried over short ...
