Phase

A term that denotes a specific stage in a cycle of a waveform, especially in the context of alternating current (AC) where it indicates the displacement between waveforms.

Parallel Circuit

A type of electrical circuit in which the components are connected alongside each other, forming branches such that each component has the same voltage.
