electric circuits
Current-carrying loops
An electric circuit is a path through which electrical current flows, typically including a power source, conductors, and components like resistors or switches.
A complete circuit forms a closed loop; a break in the path stops current flow.
The term appears in physics, electronics, and everyday contexts: The electric circuit was overloaded.
Understanding electric circuits is fundamental to electrical engineering and basic home wiring.
