Circuit

In Plain English

The complete electrical path that power travels along — from the panel to the outlet or light and back again.

Definition

A closed loop of electrical conductors through which current flows from the power source, through the load, and back to the source. Circuits consist of a hot conductor, a neutral conductor, and often a ground conductor. In AC systems, circuits are protected by overcurrent devices such as fuses or circuit breakers.
