Which of the following describes the unit of current?

The unit of current is measured in amperes, which is commonly abbreviated as "amps." Amperes quantify the flow of electric charge in a circuit, specifically indicating how much charge passes a given point in one second. This measurement is critical in understanding electrical systems, as current is essential for the operation of electronic devices and the transmission of electrical energy.

In contrast, watts are a unit of power, indicating the rate of energy transfer, joules measure energy, and volts represent the potential difference that drives current through a circuit. Understanding these units is fundamental in the study of electricity and electronics, allowing for the analysis and design of various electrical systems.
