Is proven the insolvency of the concept of the frequency dispersion of the dielectric constant of plasma and dielectrics. This error is located also in the works of Landau. Within the framework the conversions of Galileo are obtained conversions pour on upon transfer of one inertial to another. This made possible, without resorting to the conversions of Lorenz, to explain the phase aberration and the transverse Doppler effect. Is introduced new concept the scalar- vector potential of the moving charge and it is shown that the scalar potential of charge depends on its relative speed. This dependence explains physical nature of Lorentz force and power interaction of systems, along which flow the currents. It is proven that the kinetic inductance of charges is the same important parameter as dielectric and magnetic constant. The new physical concept of kinetic capacity is introduced.
