skin effect

• Effet physique en électrotechnique par lequel un courant alternatif tend à circuler près de la surface d'un conducteur, la densité de courant diminuant exponentiellement avec la profondeur.

A physical phenomenon in electrical engineering where alternating current tends to flow near the surface of a conductor, with current density decreasing exponentially as depth increases.

1. Electrical phenomenonC2formal

   The tendency of an alternating electric current to distribute itself within a conductor so that the current density is largest near the surface of the conductor and decreases exponentially with depth.

   • Engineers must account for the skin effect when designing high-frequency transmission lines.
   • The skin effect causes the effective resistance of a wire to increase at higher frequencies.
   • In radio frequency circuits, the skin effect is a critical factor in conductor selection.
