What unit is used to measure the strength of an electric current?

The strength of an electric current is measured in amperes, often abbreviated as "amps." This unit quantifies the amount of electric charge passing through a conductor in a given time. When one ampere flows through a circuit, it means that one coulomb of charge is moving past a specific point in the conductor each second.

In contrast, ohms measure electrical resistance, voltage is measured in volts and represents the electrical potential difference, while watts are used to measure electrical power, which is the rate at which energy is consumed or converted. Understanding these definitions helps clarify how amperes specifically relate to the flow and strength of electric currents in various electrical systems.
