L-2 What is Electric Current(Electrical Circuits-1) التيار الكهربى (دوائر كهربيه-1) المحاضرة الثانية

Current is the flow of electrical charge carriers like electrons. Current flows from negative to positive points. The SI unit for measuring electric current is the ampere (A). One ampere of current is defined as one coulomb of electrical charge moving past a unique point in a second. Electric current is widely used in household and industrial appliances.
