The SI unit of electric current is which of the following?

Explanation:
Current is the flow of electric charge. The SI unit that measures how fast that flow happens is the ampere, defined as one coulomb of charge passing a point every second. This clarifies why a volt measures potential difference, an ohm measures resistance, and a joule measures energy—the ampere is specifically about the rate of charge movement, not energy or force or potential. In circuits, Ohm’s law links them via I = V/R, showing how voltage and resistance determine the current, which is counted in amperes.
