Which term describes any device that stops the flow of electrons?

• A. Resistor
• B. Loads
• C. Phantom Load
• D. Open Electric Circuit

Answer: (A)

Current can flow only when the path is complete. If there’s a break in the circuit or a switch is opened, electrons can’t complete the loop, so no current flows. That situation is called an open electric circuit. A resistor, on the other hand, doesn’t stop flow entirely; it simply adds resistance and lowers the current according to Ohm’s law. A load is anything that uses electrical energy, and a phantom load is standby power drawn by devices when they’re off. So the concept being tested is recognizing that stopping electron flow means the circuit is open, not that a typical component like a resistor inherently stops current. The term that fits this description is open electric circuit.
