Electrical current is measured in which unit?

Volts
Amperes
Watts
Ohms

The correct answer is: Amperes

Electrical current is measured in Amperes, commonly referred to as "amps." The ampere is the standard unit of measurement in the International System of Units (SI) that quantifies the flow of electric charge in a circuit. One ampere is defined as the flow of one coulomb of charge per second. Understanding this measurement is crucial for anyone working with electrical systems, as it helps to dictate the capacity of wires, circuit breakers, and other electrical components to handle safe levels of current. Other options represent different aspects of electricity: Volts are the unit of measure for electric potential, Watts measure power (which is the rate of doing work or transferring energy), and Ohms measure electrical resistance. Thus, these units each play a vital role in understanding electrical principles, but they do not represent the measurement of electrical current itself.
