Electrical Circuit
A closed loop path that allows electrical current to flow from a power source to loads and back.
Full Definition
An Electrical Circuit is a closed loop path that allows electrical current to flow from a power source (like a panelboard) through conductors, switches, and loads (lights, equipment, outlets) and back to the source. Circuits are protected by circuit breakers or fuses and are organized by voltage, phase, and purpose (lighting, receptacles, equipment).
