1. In electronics: A circuit is a closed loop that allows electrical current to flow. It typically consists of components like wires, batteries, resistors, and other electronic elements.
2. In general: A circuit can refer to a route or path that is followed, often in a circular or repeating fashion. For example:
* Race circuit: A racetrack designed for motorsports.
* Electrical circuit: The path electricity takes through a device.
* Circuit court: A court of law that travels to different locations within a judicial district.
3. Other uses:
* Circuit breaker: A safety device that interrupts an electrical circuit when an overload occurs.
* Integrated circuit: A tiny electronic component that performs a specific function.
* Circuit board: A flat board containing electronic components and their connections.
Therefore, the meaning of "circuit" depends on the context in which it's used. It can refer to a path of electrical current, a route, or a specific electronic component.
