Which SI base unit measures electric current?

Explanation:
Electric current is the rate at which electric charge flows. The SI base unit for this quantity is the ampere (A). By definition, one ampere means one coulomb of charge passes a given point each second, so current is measured in amperes. The other units point to different electrical quantities: the ohm measures resistance, the volt measures electric potential difference, and the watt measures electrical power (P = VI). These relate to current through formulas like I = V/R and P = VI, but they are not base units for current.
