Which term describes stopping the flow of electrons?

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

Answer: (D)

Stopping the flow of electrons happens when the path for current is broken, so charges can’t travel through the circuit. This situation is called an open electric circuit—the circuit is incomplete, leaving a gap that prevents current from flowing even though a voltage source may be present. A resistor, in contrast, slows the flow of current but doesn’t stop it completely. A phantom load is the small amount of current drawn by devices that are off or in standby. A secondary cell is a rechargeable battery used to store and supply energy. So the idea of stopping current flow is best described by an open electric circuit.
