What Is a Short Circuit?

A short circuit is a situation where an electrical current flows abnormally through two conductors in a circuit, causing an overload. The current in the circuit travels down an undesignated pathway with minimal or no electrical resistance. A short circuit can damage the outlet, device, or light fixture, leading to a structural fire.

Closed, Open, and Short Circuits

A closed circuit allows current to flow, but an open circuit leaves electrons stranded. Picture a gallon of water flowing through an open pipe. The water will flow for a short time but then stop when all the water exits the pipe. If you pump water through a closed pipe system, the water will continue to flow as long as you keep forcing it to move.
