 the resistance increases. Since the central portion of the wire almost no current flows through  LED Downlight  this central portion can be removed to save material. Therefore, the high-frequency circuits can be used instead of a hollow solid conductor wire. Furthermore, in order to weaken the skin effect in the high frequency circuits are often mutually insulated using multiple fine wires woven into a bundle to replace the same cross-sectional area of ​​the thick wire, which is called multi-strand braided wire harness.

Third, the application of skin effect

Conductor alternating electromagnetic field intensity with depth into the conductor exponentially decreasing, so sunscreen mixed conductor particles (usually zinc oxide and titanium oxide), can make the sun's ultraviolet rays (high-frequency electromagnetic waves) the strength of the reduced. This is one of the principles of physical sunscreen. In addition, the skin effect is one of the electromagnetic shielding methods, the use of the skin effect penetration of high frequency electromagnetic wave can be prevented and made of a good conductor of electromagnetic shielding device, which is also the elevator, the reasons for poor mobile reception. In industrial applications, the use of the skin effect can be surface hardening of the metal. GU10
