What unit is used to measure electric current?

The unit used to measure electric current is the Ampere, commonly referred to as 'Amp.' It is a fundamental unit in the International System of Units (SI) and is symbolized by the letter 'A.' The Ampere measures the flow of electric charge through a conductor, indicating how many coulombs of charge pass through a given point in one second. Understanding this concept is critical for those working in electrical fields, as it allows for the assessment and management of current levels in various electrical systems and components.

Volts measure voltage, which is the electrical potential difference, while Ohms measure resistance, indicating how much opposition a circuit presents to the flow of current. Watts, on the other hand, represent power, quantifying the rate at which electrical energy is consumed or produced. Each of these units plays a significant role in electrical theory and practice but specifically measuring current falls to the Ampere.
