What is the unit of measurement for electrical current?

The unit of measurement for electrical current is the Ampere, commonly abbreviated as "Amp." It 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 concept is essential for technicians, as it allows for adequate measurements and calculations regarding the current flowing through electrical circuits.

The other terms represent different electrical properties: Volt refers to the unit of electrical potential or voltage; Ohm is the unit of resistance; and Watt is the unit of power, which quantifies the rate of energy transfer. Each of these units is important in understanding electrical systems, but when it comes specifically to measuring current flow, Ampere is the correct unit.
