what the main defination of current?
Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material.Current is a scalar quantity (though in circuit analysis, the direction of current is relevant). The SI unit of electrical current is the ampere, defined as 1 coulomb/second.
