What is the unit of electric current?

Explanation:
Electric current is the flow rate of electric charges through a conductor. The unit used for this rate in the SI system is the ampere, defined as one coulomb of charge passing a given point each second. In other words, current I equals charge Q divided by time t (I = Q/t). This makes the ampere the measurement that captures how much charge is moving per unit time. To place it in context, a volt measures the potential difference that pushes charges, an ohm measures resistance to that flow, and a watt measures the rate of energy transfer. The ampere specifically quantifies the actual flow of charge, not the driving force, the opposition, or the energy rate.
