What unit is electric current measured in?

Electric current is measured in Amperes, often abbreviated as "A." The ampere is the standard unit used in the International System of Units (SI) to quantify the amount of electric charge that flows through a conductor in a circuit over a period of time. One ampere is defined as one coulomb of charge passing through a point in a circuit in one second. This measurement is crucial in understanding how electrical systems operate, as it indicates the flow of electric charge, essential for powering devices and performing work in electrical circuits.

The other units mentioned serve different purposes: volts measure electric potential, ohms measure electrical resistance, and watts quantify the rate of electrical power consumption. Understanding these distinctions helps clarify the role that amperes play in the relationship between voltage, resistance, and power in electrical systems.
