Amperes are a measure of which electrical parameter?

• A. Voltage
• B. Power
• C. Current
• D. Resistance

Answer: (C)

Amperes, commonly referred to as amps, are units of measurement for electric current. Current represents the flow of electric charge in a circuit, and it is the rate at which electrons pass through a conductor. When a circuit is energized, the movement of these electrons constitutes the current, and the amount of flow is quantified in amperes.

Understanding this fundamental concept is crucial for electrical work, as it helps determine how much energy can be safely loaded onto circuits and ensures that systems are designed to handle varying levels of current without risk of overheating or failure. In practical applications, ensuring that current levels are within safe limits is essential for the safe operation of electrical devices and systems.
