  • zh在电工学中,交流电倾向于在导体表面附近流动的物理现象,电流密度随深度增加而呈指数衰减。

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.
