Which term describes a device or situation in which current is able to move through a circuit?

• A. Open Circuit
• B. Closed Circuit
• C. Conductor
• D. Insulator

Answer: (B)

Current flows in a circuit only when there is a complete path for electrons to travel from the source, through the conducting path, and back to the source. That situation is called a closed circuit. When a gap exists—like a switch opened or a broken wire—the path is incomplete, and current cannot flow, which is an open circuit. Conductors are materials that allow electricity to move readily, while insulators resist it. The question asks for the term describing a setup where current can move through a circuit, which is a closed circuit.
