The Summary

Electric current in metal conductor flows by means of the existent therein electronic gas characteristic by chaotic movement of electrons. Kinetic energy of the chaotic movement of electrons in a point of space makes the electric potential of the point. In a conductor, in which different places there appear electric potentials of different values there establishes a transport (diffusion) of the electrons’ energies from places with higher potentials to those with lower ones until the full equalizing of the electrons’ energies. Differences between electric potentials of different points of a conductor are electric tensions between the points. The force of electric current flowing between two points of a conductor is an amount of electrons’ energy that flows between the points for a unit of time. Electric resistance of a conductor is the ratio between the amounts of thermal energy generated in the conductor for a unit of time to the full electric energy entered the conductor for the same unit of time.

Key words:

Electric current, electronic gas, electric potential, force of current, tension, electric resistance, electrons’ energy, metal conductor, Law of Ohm, First Law of Joule.

How the Ether Friendly Phisics imagine electric current flowing through metal conductor

As writes the Wikipedia [1], “A solid conductive metal contains mobile or free electrons, which function as conduction electrons. These electrons are bound to the metal lattice but no longer to an individual atom. Metals are particularly conductive because there are a large number of these free electrons, typically one per atom in the lattice. Even with no external electric field applied, these electrons move about randomly due to thermal energy but, on average, there is zero net current within the metal. At room temperature, the average speed of these random motions is 10 6 meters per second. Given a surface through which a metal wire passes, electrons move in both directions across the surface at an equal rate. As George Gamow wrote in his popular science book, One, Two, Three...Infinity

(1947), "The metallic substances differ from all other materials by the fact that the outer shells of their atoms are bound rather loosely, and often let one of their electrons go free. Thus the interior of a metal is filled up with a large number of unattached electrons that travel aimlessly around like a crowd of displaced persons. When a metal wire is subjected to electric force applied on its opposite ends, these free electrons rush in the direction of the force, thus forming what we call an electric current."

When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor. The moment contact is made the free electrons of

2 the conductor are forced to drift toward the positive terminal under the influence of this field. The free electrons are therefore the charge carrier in a typical solid conductor.”

EFP agrees with the above stated views about the existence in metals of free electrons with a decisive role in the electric current formation. Furthermore according to our vision the free electrons form in metals a kind of electronic gas, in which gas the principal distinctive feature would be the electron’s energy. The chaotic movement of electrons in such a gas is in our opinion the most effective means for the diffusion of energy from places with quicker electrons to places with slower ones. The EDP cannot consent to the idea that electric current is a transport of charges, at least because it had already demonstrated [2] that the notion of electric charge similarly to that of mass is artificially concocted in a substitution to geometrical characteristics of respective material bodies, particularly electrons.

Moreover the EFD believes that electric current is not even a transport of electrons. According to our views it is transport of electrons’ energy.

According to modern views electric current is a flow of electric charges from places with higher electric potential (with higher potential electric energy) to places with lower electric potential. Difference between higher and lower potentials is known as electric tension. EFP assumes that under electric potential one ought to understand the energy of electrons in a respective point of a conductor. If a kinetic energy of electrons at the beginning of a conductor reveals itself greater that at its end the current would flow from the beginning to the end of the conductor, and such a current would not be that of electrons but that of their energies, and it will go on flowing until the electrons’ energies at the conductor’s ends become equal.

From the above stated results that if according to modern views under the electric current in some place of a conductor one means the amount of electric charges flown through this place for a unity of time, then according to EFD under the electric current in this place of the conductor one ought to mean the amount of energy flown through it for a unity of time that is power.

What is electric resistance and how are interconnected the Law of Ohm and the First Law of Joule

As it is known the Law of Ohm establishes interdependence between current , which according to modern views relates to the amount of electric charges, i.e. electrons that flow through a metallic conductor for a unit of time, whereas according to our opinion it is the quantity of electrons’ energy that flows for a unit of time through the end of the conductor (point 2), and tension that represents the difference of potentials at the beginning (point 1) and the end of the conductor = − , which according to our opinion is the amount of electric energy that flows for the same time through the beginning of the conductor

= (1).

In the here shown formula to the item is assigned a role of the resistance offered by a conductor to flow there through of an electric current, and the generally used unit of such resistance is ohm.

It is known that current flow through metallic conductor is accompanied with generation therein of thermal energy and that the amount of this energy agrees with a formula

= (2),

3 that is mathematical expression of the First Law of Joule. Actually the conductor’s warming during the flow there through of electric current is provoked by its resistance, although no connection between the formulas (1) and (2) may be noticed in today scientific and technical literature.

In our view the situation may be explained as follows. The energy starting to flow through the conductor in point 1 reaches point 2 suffering some losses, of which the heaviest ones are thermal losses . We may assume that the relation between the thermal losses and the full amount of the entered energy may represent the value of the resistance .

= (3).

Then = and taking into account that according to the Law of Ohm = we come to the First Law of Joule (2).

The expressed ideas allow making series of other interesting conclusions that do contradict neither the

Law of Ohm, nor the First Law of Joule and which mathematical formulations would be

= + ; = − ; = − ; = ; = ( − 1) .

CONCLUSIONS:

1) Electric current in metal conductor flows by means of the existent therein electronic gas characteristic by chaotic movement of electrons;

2) Kinetic energy of the chaotic movement of electrons in a point of space makes the electric potential of the point;

3) In a conductor, in which different places there appear electric potentials of different values there establishes a transport (diffusion) of electrons’ energy from places with higher electrons’ energies to those with lower ones until the full equalizing of the electrons’ energies.

4) Differences between electric potentials of different points of a conductor are electric tensions between the points.

5) The force of electric current flowing between two points of a conductor is an amount of electrons’ energy that flows between the points for a unit of time.

6) Electric resistance of a conductor is the ratio between the amounts of thermal energy generated in the conductor for a unit of time to the full electric energy entered the conductor for the same unit of time.
