In most metals, electrons are the majority charge carrier, but that's not the case for all materials. For example, in pure water, there aren't free electrons, and the charge carriers are H + and OH − ions. There are not many ions in pure water, so it's a poor conductor.

WebCurrent or dynamic electricity is defined as an electrical charge in motion. It consists of a flow of negatively charged electrons from atom to atom through a conductor in an electrical circuit. The external force that causes the electron current flow of electric charge is called the electromotive force (emf) or voltage. Web1) The electric current is flow of electrons in metal wires, (or in fluids like electrolytes). The electrons are moving in the wire at the drift velocity v = I e n A where: I is the electric current; e is the elctric charge on the electron; n is the electron number density in the metal material of the wire; A the cross section area of the wire.
