A circuit is best defined as

• A. A circuit
• B. A path for an electrical current to flow around
• C. A device that uses electrical energy to do work
• D. A source of energy

Answer: (B)

At its core, a circuit is a closed loop that allows electric current to travel from a source, through conductors and any loads, and back to the source. Current only flows when the path is continuous; any break stops the flow. The best description here is a path for an electrical current to flow around, because it captures the essential idea of a loop that supports continuous current. The other options describe parts of a circuit or the energy source alone, not the complete path that makes current flow.
