What is a characteristic of a closed circuit?

A closed circuit is defined by its ability to provide a complete and uninterrupted path for electric current to flow. This characteristic is crucial in electrical and electronic systems because it allows devices to function correctly. When a circuit is closed, there are no breaks or interruptions in the pathway, enabling the consistent delivery of electricity to components like lights, motors, and other devices.

The continuous path for current distinguishes closed circuits from open circuits, where one or more connections are broken, preventing current flow. Recognizing that closed circuits are foundational for the operation of most electrical systems helps reinforce the importance of maintaining this integrity in circuit design and troubleshooting.
