In terms of voltage, what does "Hot" refer to?

• A. A wire with 0 volts.
• B. A wire that is grounded.
• C. A live wire carrying 120 volts.
• D. A dead circuit with no voltage.

Answer: (C)

"Hot" refers to a wire that is carrying an electrical current, typically at a voltage level that can create a shock hazard. In standard North American household wiring, a "hot" wire typically carries 120 volts for general circuits. This is the voltage present when the wire is energized and capable of delivering electrical power to devices and appliances. Understanding this concept is crucial for safely working with or around electrical systems. Recognizing which wires are "hot" allows one to take appropriate precautions to prevent electrical shocks or accidents. The term "hot" clearly indicates a live electrical line, making option C the correct interpretation of what "hot" signifies in the context of voltage.
