Which statement is true about the condition of current flow in a closed circuit?

• A. Current flows when the circuit is open
• B. Current flows when the circuit is closed
• C. Current does not flow in a closed circuit
• D. Current can flow regardless of circuit type

Answer: (B)

Current flows when the circuit is closed because a closed circuit provides a complete path for electricity to flow. This path allows electrons to move from the power source, through the conducting materials (such as wires) and to the load (like a light bulb or motor) and back again. When the circuit is closed, the conductive pathway enables the potential difference (voltage) to cause current to flow. In contrast, when the circuit is open, the path is incomplete, preventing current from achieving continuous flow. This is essential for the operation of any electrical device. Current cannot flow if the pathway is interrupted, which means that the concept of a closed circuit is fundamental to understanding how electrical systems operate.
