what is the s.i unit of electric current
Electric current The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.[3]
Watt The watt (symbol: W) is a derived unit of power in the International System of Units (SI) defined as 1 joule per second[1] and can be used to quantify the rate of energy transfer. Power has dimensions of    M L  2   T  − 3   {\displaystyle {\mathsf {ML}}^{2}{\mathsf {T}}^{-3}} .
