In the SI system, what is the unit for electric current?

In the SI system, the unit for electric current is indeed amps, denoted by the symbol A. Electric current is defined as the flow of electric charge, and the ampere represents one coulomb of charge moving past a given point in one second. This definition links the unit directly to the amount of electric charge and the time it takes for that charge to flow, which is fundamental to understanding electricity and electrical circuits.

The other units listed correspond to different electrical properties: volts measure electric potential or voltage, ohms quantify electrical resistance, and watts represent power or the rate at which energy is transferred. Each of these units serves a distinct purpose in the study of electricity, whereas amps specifically quantify current.
