The history of the idea of electric current, of flow, transport, orderly movement of electric charges.
The idea begins with Stephen Gray's experiment, which polarizes
the beginning of a long wire and finds the effect at the other end of the wire.
The good sense shows that the electricity is something that "travels" through wires.
The lack of knowledge about the electrical phenomenon,
gave exclusivity to the research of the transport idea.
François de Cisternay du Fay noted the existence of two types of electricity.
Benjamin Franklin contradicts it with decisive explanations,
which have convinced the scientific world since then.
The one who decides the identify electricity with electrical charges is Hendrik Antoon Lorentz:
"Electricity is made up of material particles with a defined charge and mass."
Stephen Gray's experiment had the alternative to the idea of transport, shown in the drawing below.
Stephen Gray electrostatically polarizes the wire over its entire surface,
but looks for the (preconceived) effect only at the other end.
The wire had received information, the direction of polarization (positive or negative),
transmitted from close to close (domino effect), with the speed of light.
The empirical achievements and the reason, that there is no alternative, stopped the criticism.
The laws of electromagnetism are interpreted exclusively by the movements of the "electron".
Ohm's law says that the intensity is directly proportional to the voltage
and inversely proportional to the resistance.
The drawing shows the vectorial nature of the relationships between intensity, voltage and resistance.
Intensity I, represents the density of the electrically oriented polarities in the section.
Intensity B, represents the density of the magnetically oriented polarities.
The voltage U, represents the centripetal EM force, the pressure, which orients the polarities of the EM.
Resistance R, represents polarities of atomic bonds, which oppose the orientation of the polarities EM.
"Black holes", the electroide, are not what we call matter!
They are energy with vector properties, oriented wth unique sense, into closed circuit (electromagnets).
In these cosmic electromagnets, Ohm's law becomes: I = U (EM pressure !!!)
We can't even imagine what forces, what energies the universe contains!
The atoms to the elements are insignificant by-products and we invent elementary particles.
The laws electromagnetic are fundamentals and simple,
but we complicate them (gravity, the electric current, etc.).
