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

The strength of an electric current is measured in amperes, commonly referred to as "amps." This unit quantifies the flow of electric charge in a circuit. Specifically, one ampere corresponds to one coulomb of charge passing through a point in a circuit per second. Understanding electric current is essential in esthetics, especially when working with devices that utilize electricity, as it helps professionals gauge safe and effective usage of equipment.

In contrast, volts measure the electrical potential difference, or the force that pushes the electric current through a circuit. Watts represent the power, or the rate at which electrical energy is consumed or converted, whereas ohms measure resistance, which is the opposition to the flow of current. Each of these units plays a vital role in the principles of electricity, but when specifically discussing the strength of electric current, amperes are the precise and appropriate measure.
