Which unit measures the strength of an electrical current?

The strength of an electrical current is measured in amperes, commonly referred to as "amps." The ampere quantifies the flow of electric charge in a circuit, indicating how much current is flowing at any given moment.

In the context of electrical systems, current is a fundamental parameter, and understanding it is crucial for safely operating electrical devices and systems. The ampere provides a clear metric to describe how much electrical flow is present and is essential in calculations involving power, resistance, and energy use in circuits.

Other units, such as volts, ohms, and watts, relate to different aspects of electricity. Volts measure electrical potential, ohms measure resistance, and watts measure power, which is the rate at which energy is used or produced. While they all have important roles in electrical circuits, they do not directly quantify the flow of current like amperes do.
