An electrical circuit in which there is no interruption of current flow.

An electrical circuit in which there is no interruption of current flow.

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

Answer: (C)

Current flows only when there is a complete path for electrons to travel. When the conductor loop is continuous from the energy source, through all components, and back to the source, there’s no break in the path, so current can flow steadily. That situation is a closed circuit. If there’s any gap—like an open switch or a broken wire—the path is interrupted and current stops, which is an open circuit. The terms for how components are arranged (series or parallel) describe layout, not whether the current path is complete; both require a closed loop to allow current. So describing “no interruption of current flow” points to a closed circuit.
