What Is Skin Effect?

Skin effect is a condition where A.C (alternating Current) tents to travel on the surface of the conductor, as frequency increases.

It is easy to explain by comparing the resistance between these 3 scenarios DC Resistance, AC Resistance in Low-frequency and AC Resistance in High-frequency.

At high frequencies the AC current avoids travel through most of the conductor's cross-sectional area. Therefore, the conductor might as well to be hollow for transmitting current at high frequencies.

At some point, using the high frequencies in transmitting current might reduce the cost of conductor since the conductor itself is not a solid conductor.
