The path followed by electrons from a power source such as a photovoltaic (solar) panel, through an electrical system to create light, motion, battery power, and other power. The circuit is completed when the electrons return to the power source, creating a continuous flow of electricity.

The complete path of an electrical current. An electrical circuit is considered to be an open circuit when the continuity is broken and a closed circuit when continuity is maintained.

A closed, conducting path or route through which an electric current travels.

A complete path followed by electrons from a power source to a load and back to source.
