WebElectric current is kind of like water current. When we talk about water current we treat the water as a continuous fluid, not as a collection of water molecules. We have units for current like gallons per minute or liters per second. You pretty much never measure current in molecules/second.
WebElectricity is a form of energy. It is the phenomenon that describes the flow of charged particles (particularly electrons) from one place to another. The SI base unit of electric … christian gaudin centhysIn metallic solids, electric charge flows by means of electrons, from lower to higher electrical potential. 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.
