The flow of electrical current is measured in?

Amperes
Ohms
Volts
Watts

The correct answer is: Amperes

The flow of electrical current is measured in amperes, which is the standard unit of measurement for electric current in the International System of Units (SI). Amperes quantify the amount of charge that flows through a conductor in a given time period. Specifically, one ampere represents one coulomb of charge passing through a point in a circuit each second. Understanding this concept is critical in the context of water treatment and electrical systems, as managing and measuring electrical current is essential for ensuring the proper operation of equipment such as pumps, sensors, and treatment facilities. In contrast, ohms measure electrical resistance, volts measure electrical potential or voltage, and watts measure electrical power, which is the product of voltage and current. Each of these units plays a different role in understanding electrical systems, but amperes specifically denote the flow of current itself.
