Bundled conductors skin effect

WebSkin depth, denoted by the symbol δ, is a measure of skin effect and is the depth at which the current density is 1/e of the current density at the surface of the conductor. Note: “e” is the mathematical constant that is the base of the natural logarithm (“LN” on my scientific calculator) and is equal to about 2.718, so 1/e ≈ 37%. WebThis video explains the skin effect in Transmission Lines. It also highlights different causes of the skin effect and the factors that affect the skin effect...
