Which term describes a closed, conducting path?

• A. Wire
• B. Path
• C. Circuit
• D. Loop

Answer: (C)

A circuit is a closed, conducting path that allows electric current to flow. When conductors connect a power source to components, they form a complete loop so electrons can travel and return to the source. If there’s a gap, the path isn’t complete and current can’t flow. A loop or a wire by itself isn’t guaranteed to be a working, closed conducting path, so circuit is the precise term for this concept.
