Which term describes a circuit that allows electric current to flow?

• A. Open circuit
• B. Parallel circuit
• C. Short circuit
• D. Closed circuit

Answer: (D)

Electric current needs a complete path to move. When the circuit is closed, the loop from the power source through conductors and components back to the source is continuous, so electrons can flow and devices work. An open circuit has a gap, stopping the flow; a short circuit is an unintended low-resistance path that can cause excessive current; and a parallel circuit refers to how branches are arranged rather than whether current can flow in the loop. So, the term that describes a circuit that allows electric current to flow is closed circuit.
