Electric current - Wikipedia

An electric current is a flow of charged particles, ... In other media, any stream of charged objects (ions, for example) may constitute an electric current. To provide a definition of current independent of the type of charge carriers, conventional current is defined as moving in the same direction as the positive charge flow. So ...

Electric Current - GeeksforGeeks

So by the definition of Electric Current, its unit is Coulomb/second. In the SI Unit of Electric Current is Ampere (A). In the CGS system, the unit of Electric Current is B iot or sometimes called an Abaampere. If 6.241 x 10^18 electrons flow through a conductor in one second, the electric current passing through it is defined as one ampere.
