In what unit is electric current measured?

Electric current is measured in amperes (often abbreviated as "amps"). The ampere is a fundamental unit in the International System of Units (SI) and represents the flow of electric charge. When one ampere of current flows through a conductor, it means that one coulomb of charge is passing through that point in the circuit per second.

To understand the other units: volts measure electric potential or voltage, watts measure electrical power (the rate at which energy is used or generated), and ohms measure resistance in a circuit. Each of these units plays a different role in understanding electricity, but when specifically discussing the flow of electric current, amperes is the appropriate measurement.
