Which term describes a circuit where the path is broken so current does not flow?

Explanation:
When the path for current is broken, the circuit is open and no current can flow. Electrons have nowhere to travel in a complete loop from the power source, through any devices, and back to the source. That break stops the continuous path, so even though the power source might still be energized, the circuit behaves as if it’s inactive and the connected devices don’t operate. This concept contrasts with a closed circuit, where a complete loop allows electrons to move and current to flow. Topics like static electricity describe charge buildup on surfaces rather than the continuity of a conducting path, and an uncharged object refers to the absence of net charge, not whether the circuit is complete.
