Circuit: meaning, definitions and examples

Use 'circuit' when referring to a closed path through which an electric current flows. Often used in the context of electronics and electrical engineering.

• The engineer designed a new circuit for the radio.
• The circuit was complete, allowing the current to flow through.

The term 'loop' is appropriate for programming to denote repeated sequences of instructions or in electronics for circular pathways in circuits. It can also refer to routes or paths that begin and end at the same point.

• The loop in the program caused it to run indefinitely.
• The electrical loop was tested for breaks.

Choose 'circuitry' when discussing the complex system of electronic circuits collectively, often found within devices.

• The smartphone's internal circuitry is very sophisticated.
• He specializes in the study of advanced circuitry.

Use 'network' when describing a complex, interconnected system of components such as computers, people, or electrical elements collaborating to perform tasks.

• The office has a secure computer network.
• They set up a network of sensors to monitor the environment.

Used describing a smaller, interconnected group within a larger electrical system.

• This circuit is responsible for the lighting system
• A short circuit caused the power outage

Used when referring to an entire set of connected electrical components that work together as a whole, more broadly than a single circuit.

• The security system uses multiple sensors and cameras
• She designed a new system for home automation

Used when referring to a physical platform that holds and connects electronic components, like in a computer or other electronic devices.

• The main board is damaged and needs to be replaced
• You need to solder the components onto the board

Used for small, complex electronic devices that have many integrated circuits, usually made from silicon.

• The computer needs a new chip to improve its processing speed
• This tiny chip can hold an enormous amount of information

Used in contexts involving electrical systems, racing tracks, or routes that form a complete path.

• The electrician checked the circuit to ensure there was no fault.
• The racing driver completed the circuit in record time.

Refers to a round shape with no beginning or end, can also be used metaphorically in social contexts.

• She drew a perfect circle on the paper.
• They gathered in a circle to discuss their plans.

Typically indicates a shape that curves back on itself or a sequence that repeats continuously, common in programming and design.

• The programmer wrote a loop to repeat the process.
• The roller coaster features a thrilling loop.

Used to describe the action of spinning around a center or pivot, often relating to planets or objects in rotation.

• The Earth revolves around the Sun.
• The dancer seemed to revolve in mid-air.
