What unit is electric current measured in?

Electric current is measured in amperes, often abbreviated as "A." This unit defines the flow of electric charge in a circuit. Specifically, one ampere is equivalent to the flow of one coulomb of charge per second. It is a fundamental quantity in electrical physics, as it quantifies how much charge is moving past a given point in a circuit within a certain time period.

Understanding electric current in terms of its unit, amperes, is crucial for analyzing electrical systems and circuits. In practical applications, measuring current in amperes helps in determining the performance of electrical devices and in ensuring safe and efficient operation within the circuit.

The other units mentioned serve different roles: volts measure electric potential difference, watts quantify electrical power (the rate at which energy is used or transferred), and ohms represent electrical resistance. Each of these concepts relates to current but does so from different perspectives in the context of electricity.
