A condition caused by a break in a circuit causing current to stop flowing is known as a/an ____________.

• A. Short circuit
• B. Open circuit
• C. Ground fault
• D. Leakage

Answer: (B)

When the conducting path in a circuit is interrupted, the loop isn’t complete and current cannot flow. That situation is called an open circuit. It’s different from a short circuit, where a low-resistance path causes a surge of current rather than stopping it. A ground fault means current leaks to the earth through an unintended path, not a complete break, and leakage is small, unwanted current that still may flow even with a closed loop. So the condition described—a break in the circuit causing current to stop flowing—fits an open circuit.
