Current in an electrical circuit is measured in what unit?

Current in an electrical circuit is measured in Amperes, commonly referred to as "amps". This unit quantifies the flow of electric charge in a circuit. One ampere is defined as one coulomb of charge moving past a point in one second. The importance of measuring current in amps lies in its ability to indicate not only the amount of electricity flowing but also to help determine a circuit's performance and safety.

In contrast, volts measure electrical potential or voltage, watts measure power (which is the product of voltage and current), and ohms measure resistance, which impacts how much current flows for a given voltage in a circuit. Understanding these distinctions is crucial for analyzing and designing electrical systems.
