What is the unit of electrical current?

Explanation:
Current is the rate at which electric charges flow through a conductor, so its unit is the ampere. One ampere means one coulomb of charge passing a point each second. That direct relationship—coulombs per second—defines the current unit, written as amperes (A). Volts measure electric potential difference (the pressure that pushes charges), ohms measure resistance (how much a material resists the flow), and watts measure power (the rate energy is used or transferred). Since the question asks about the unit for current, amperes is the correct choice.
