skin effect

Question

At high frequencies current tends to concentrate:

RankGuru · Accepted Answer

The **Skin Effect** is the tendency for alternating current to flow primarily near the surface of a conductor.
- This happens because the changing current produces a changing magnetic field inside the conductor, which in turn induces eddy currents that oppose the main current at the center and support it at the edges.
- It becomes more pronounced at higher frequencies, effectively increasing the AC resistance of the wire.
