What is the unit of measurement for electrical current?

The unit of measurement for electrical current is the Ampere. This unit quantifies the flow of electric charge in a circuit. One Ampere is defined as one coulomb of charge passing through a point in a circuit per second. Understanding this is crucial in HVACR applications, where the current determines how much energy is being used by electrical components.

In the context of circuits, Ohms measure resistance to current flow, Volts measure electrical potential or voltage, and Watts measure the power consumed in an electrical system. Thus, Ampere is specifically focused on the current aspect, making it the correct choice. This distinction is essential for HVACR professionals when diagnosing and working with electrical systems, as the efficient operation of equipment often depends on the proper understanding of current flow.
