Skin effect is the tendency of a high-frequency alternating current to flow through only the outer layer of a conductor. It is more predominant in AC transmission.
When an AC current is passing through a conductor distributes non-uniformly throughout the conductor. And it is dependent of frequency, it is more in high frequency transmission.

AC Current Distribution in a Conductor
Uniformity of Current Distribution:
AC current passing through a conductor distributes non-uniformly throughout the cross-section. The distribution of current is not uniform because of the skin effect.
Skin Effect:
The skin effect is a phenomenon where the current density is maximum (or skin depth is minimum) at the surface of the conductor and decreases exponentially as we move towards the center of the conductor. This effect is more pronounced at higher frequencies.
Frequency Dependency:
The frequency of the AC current passing through the conductor affects the skin depth, which, in turn, affects the current distribution. The higher the frequency, the shallower the skin depth, and the more pronounced the skin effect.
Conclusion:
Therefore, we can conclude that the AC current passing through a conductor distributes non-uniformly throughout the cross-section and is frequency-dependent due to the skin effect.
