Electrical current is measured in which of the following units?

Electrical current is measured in amperes, often abbreviated as "amps." An ampere is defined as the flow of electric charge through a conductor over time. When current flows, it represents the movement of electrons through a circuit, and the unit of reference for this flow is the ampere.

To understand this in the context of other electrical units: volts measure the electric potential or pressure that drives the current through the circuit, watts quantify the total power consumed or produced in the circuit based on the current and voltage, and ohms measure the resistance that opposes the flow of the current. Thus, when discussing the specific measurement of electrical current itself, amperes is the correct unit to use.
