Definitions:

In Phase

A condition that occurs when voltage and current reach all peak values at the same time.

Out of Phase

A condition where two waveforms of the same frequency are not aligned in time, resulting in a phase difference.

Leading Phase

A condition in an AC circuit where the voltage wave is ahead of the current wave in time, indicating capacitive properties.

Skin Effect

The tendency of an alternating electrical current to become distributed within a conductor such that the current density is largest near the surface of the conductor, and decreases with greater depths in the conductor.
