What is the unit used to measure electric current?

The unit used to measure electric current is the Ampere, which is often shortened to "Amp." An Ampere quantifies the flow of electric charge in a circuit. Specifically, it measures how many coulombs of charge pass through a conductor per second. This unit is fundamental in understanding electrical circuits, as current is one of the key parameters in analyzing how electricity travels through systems.

Understanding the relationship between current and other electrical quantities is crucial. For example, volts measure voltage, which is the potential difference that drives the current through a circuit. Ohms measure resistance, which opposes the flow of current. Farads, on the other hand, measure capacitance, which relates to how much charge a capacitor can store. Each unit plays a distinct role in the study of electricity, but when it comes to measuring the flow of electric current specifically, the Ampere is the correct and indispensable unit.
