What is the measurement unit for electrical current?

The measurement unit for electrical current is an amp, which is short for ampere. This unit measures the flow of electric charge in a circuit. Specifically, one ampere is defined as the flow of one coulomb of charge per second. Current is a fundamental concept in electrical theory, and it describes how much electric charge is moving through a conductor.

Understanding current is essential for various applications, including circuit design and troubleshooting, since it helps determine how much electricity is flowing and influences factors such as heat generation and energy consumption in electrical devices.

The other options relate to different electrical properties: an ohm measures resistance, a hertz measures frequency, and a volt measures electrical potential difference. Each of these units plays a role in the broader study of electricity, but only the amp specifically quantifies electrical current.
