The unit of electric current is known as the Ampere, often abbreviated as "Amp." The Ampere is defined as the flow of electric charge through a conductor. Specifically, one Ampere is equal to one coulomb of charge passing through a point in a circuit per second. This unit is a fundamental measurement in electrical engineering and physics, as it quantifies the amount of electricity being transferred in a circuit, which directly impacts the functionality and efficiency of electronic devices and systems.

Understanding the role of current in electrical circuits helps to analyze and design systems effectively, making the Ampere a critical unit in the study of electricity. The other units listed, such as Volt, Watt, and Ohm, serve different purposes: Volt measures electric potential, Watt measures power (the rate of energy transfer), and Ohm measures resistance. Each has its distinct role in the broader context of electric circuits.
