Define the term "amperage."

The term "amperage" refers to the measure of electrical current. In electrical systems, current is the flow of electric charge, and it is quantified in amperes, often abbreviated as "amps." Understanding amperage is crucial in HVAC applications, as it directly relates to how much electrical energy is being used by devices and systems.

When dealing with circuit design, amperage helps determine if a circuit can handle the load. If the current exceeds the amperage rating of components or conductors, it can lead to overheating and potential failure. Therefore, monitoring and managing amperage is essential for safe and efficient operation in electrical systems.
