The universal behavior of the electronic transport in solids is discussed. It is shown that these findings can be interpreted by a general quantum transport model. It is based on a generalization of the Bohr quantum condition, resulting in a reference length a_e = 7.25 nm and a reference electron density of 3 × 10¹⁵ m^-2, which limits the electron current. It is shown that the limitation is supported by experimental data. The priority of the formulation of the square of the electric charge as e² = αh is discussed. It leads to a new system of units. The formulations of the reference values of all electromagnetic quantities are given. It is shown that the data of the Aharonov Bohm effect of 1/f noise confirm the presented statements.
