The "normal skin effect" is a term used to describe the tendency of high-frequency alternating current to flow along the surface of a conductor rather than through its center. This effect can lead to increased resistance and energy losses in some electrical components. Synonyms for the term might include "skin effect," "surface effect," or "skin depth effect." Other related terms could include "high-frequency attenuation," "eddy currents," or "magnetic hysteresis." Understanding these concepts can be important in fields such as electrical engineering, telecommunications, and radio-frequency design, where efficient transmission of signals is a key concern.
