Definition
- Noun:
- An electrical device that provides a path for electrical current to flow: An electric circuit is a complete, closed loop through which an electric current can travel. It typically consists of a power source (like a battery), conductors (like wires), and components (like resistors or light bulbs) that use the electrical energy.
Usage Examples
- Noun:
- The engineer designed a new electric circuit for the amplifier.
- A basic electric circuit requires a power source, wires, and a load.
- If there is a break anywhere in the electric circuit, the current will stop flowing.
Advanced Usage
- "To complete a circuit": To close the loop so that current can flow continuously.
- When you flip the switch, you complete the circuit and the light turns on.
- "Open circuit": A circuit that is broken or interrupted, preventing current flow.
- The device won't work because there's an open circuit in the wiring.
- "Short circuit": A fault where current flows along an unintended, low-resistance path.
- A short circuit caused the fuse to blow.
