What is the magnitude of current measured in?

The magnitude of current is measured in Amperes. This unit defines the flow of electric charge in a circuit. One Ampere is equivalent to one coulomb of charge passing through a given point in a circuit per second. It is a fundamental measurement in electrical and electronic systems, representing how much electric charge is flowing.

The other units mentioned—Watts, Volts, and Ohms—measure different electrical properties. Watts measure power, which is the rate at which energy is consumed or converted. Volts measure electrical potential difference or voltage, which reflects the potential energy per unit charge available to drive current through a circuit. Ohms measure resistance, indicating how much a material opposes the flow of electric current. Each of these units plays a crucial role in understanding electrical systems, but for measuring current specifically, Amperes is the correct and standardized unit.
