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.
Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
