What unit is used to measure electrical current?

The unit used to measure electrical current is referred to as "Amps," derived from the name of the French physicist André-Marie Ampère. Amps quantify the flow of electric charge in a circuit, essentially representing how much electricity is flowing. This measurement is fundamental in electrical engineering and various applications, as it helps determine the amount of current that can safely flow through wires and components without causing damage or overheating.

The other options represent different electrical concepts: Volts measure electrical potential or voltage, Ohms measure resistance, and Watts measure power, which is the rate at which electrical energy is used. Each of these units plays a crucial role in electrical systems, but when focusing specifically on measuring current, Amps is the correct unit to use.
