Which of the following is the SI unit of electric current?

Explanation:
Electric current is the rate at which electric charges flow through a point in a circuit. The SI unit for this rate is the ampere, defined as one coulomb of charge passing a point every second. This directly ties to the idea of flow: current tells you how much charge moves per unit time. The ampere name comes from a scientist, and it relates to the fundamental units of charge (coulomb) and time (second). The other units measure different things—volt is potential difference (the push that drives charges), joule is energy, and ohm is resistance. So the ampere is the correct unit for electric current.
