Skin effect – Wikipedia

Posted by jpluimers on 2019/09/23

Skin effect – Wikipedia:

Skin effect is the tendency of an alternating electric current (AC) to become distributed within a conductorsuch that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor. …

At high frequencies the skin depth becomes much smaller. … Because the interior of a large conductor carries so little of the current, tubular conductors such as pipe can be used to save weight and cost.
