Abstract
At present time the concept of an electric current of a conductor does not correspond to physical essence of the phenomenon. It is considered to be, that the electric current on a conductor is transmitted by moving electrons that is by material particles. But the matter motion at transmission of electric energy on a conductor has been never fixed. It is considered to be, that electron comes off one atom and passes to other atom. However the detach of electron from atom can occur only by ionization or an exposure, and in a conductor with a current such exposure (even the instant) does not leave any traces. Transmission of electric energy through a current conductor is accompanied by thermal energy output. However now the reasonable explanation of thermal energy output is absent. It is offered to present an electric current on the basis of the quantum theory as a transmission of energy by matter particles without matter motion and without ionization and also to explain the thermal energy output at electric current passing through conductor.
