skin effect

Definition

Electronics

  • The tendency of AC to flow near the surface of a conductor. This effect becomes more pronounced as frequency rises, so losses due to resistance become greater with frequency increases. A conductor made from many separately-insulated wire strands which are woven together or braided in a manner that each strand regularly assumes each of the possible positions within the overall cross section of the conductor minimizes this effect, providing for lower losses at radio frequencies. Also called conductor skin effect.
