In what unit are electrical currents measured?

1. Volts

2. Amperes

3. Watts

4. Ohms

The correct answer is: Ohms

Electrical currents are measured in Amperes, which is the correct unit for this purpose. Amperes, often referred to simply as "amps," quantifies the amount of electrical charge that flows through a circuit over a given period of time. It is a fundamental measure in understanding electrical systems and their capacity to convey electric charges. While other units such as volts, watts, and ohms are related to electricity, they measure different aspects: volts measure the electric potential or pressure, watts measure power (the product of voltage and current), and ohms measure resistance. Understanding these terms in relation to amperes allows for a better comprehension of how electrical systems function and the interplay between these different measurements.
