What does "hot" mean in electrical terms?

In electrical terms, "hot" refers to a wire that carries voltage. This means that the wire has electrical potential and can deliver current to a circuit, which is necessary for powering devices and appliances. Hot wires are typically colored black or red in residential wiring standards, indicating that they are energized and should be handled with caution to avoid electrical shock.

The concept of "hot" is fundamental to understanding electrical systems, as it distinguishes the wires that supply power from those that do not. A properly functioning electrical circuit relies on the hot wire to complete the pathway needed for the flow of electricity, allowing devices to operate as intended.

Understanding this definition is crucial for anyone working with electrical systems, as it emphasizes safety measures and the importance of correctly identifying wire functions during installation or maintenance.
