Greetings to you friends. In this article I want to pay attention to such a concept as an electric current and what is wrong with it. I do not consider the generally accepted theories that are taught in school, it's not interesting and childish. My attention is attracted not by the concatenation in these theories and the logical explanation of the phenomena. For those who forgot to recall, according to the school subject "Physics" for the 8th grade, "Current strength (I) is a scalar quantity equal to the ratio of the charge (q) passing through the cross section of the conductor to the time interval (t) during which there was a current ".
I = qt, where I - current strength, q - charge, t - time.
The current unit in the SI system is [I] = 1A (ampere). We remembered, perfectly, now we will pass our time.

Scheme 1 shows the source of electrical current and resistance. When applied to points 1-2 potentials, provided that there is a difference between them, which is created by our current source, an electric current flows through resistance (P), which is equivalent to determining the motion of an electric charge. I want to immediately draw attention to the fact that the concept of "flowing" is not in vain used by people, since this is exactly the idea of ​​the electric current we have. If we connect an ammeter to the circuit, we can determine the current strength. The current can be calculated using Ohm's Law (see Figure 1).
As can be seen from the Ohm's equation, the electric current strength is directly proportional to the potential difference and is inversely proportional to the resistance. In the formula, the resistance of the circuit is formed by the sum of the resistance of the current source (p) and the intrinsic resistance of the external circuit (P). Next, for reasoning, we will use resistance. The resistance in fact does not depend on the strength of the current and the potential difference, it is determined by the properties of the material and its dimensions. The formula for calculating the resistance figure 2. I want to note that the formulas in Physics have experimental confirmation that there should not be any doubt about their fidelity.

Electrical resistance
According to the formula, the resistance depends directly on the length (L) of the conductor and inversely proportional to the cross-sectional area (S) of the conductor through which the current flows. In the same figure 2, I depicted two conductors with different geometric parameters. The dimensions of the conductor, the length and the cross-sectional area are correspondingly twice as large as the dimensions of the conductor 1. If we substitute these values ​​in the formula for calculating the resistance of the conductor and provided that they have the same resistivity (for example, for copper p = 0.0017 Ohm mm2 / m) , then we note that the resistance has not changed. From this we can draw the following conclusion, if the applied potential difference and resistance are equal, then the current strength will be the same for 1 and 2 conductors. And here you can see a similarity with the Bernoulli equation, where exactly the same dependence exists.
I recall that according to Bernoulli, when an incompressible fluid flows through different sections of the tube, the velocities are inversely proportional to these cross sections. The larger the cross-section of the tube, the lower the flow velocity through this tube. We have already met this word "leak" when talking about the strength of the current.
Conclusions. From the above, the following conclusion suggests that the current flow rate in the conductor is not constant. The difference in speed due to the geometric dimensions of the conductor with the same resistance, can reach huge values. When the area of ​​the conductor is increased by a factor of 10, the speed should decrease by a factor of 10. But we know everything from the same Physics, from the school bench, that the speed of electric current is equal to the speed of light, which is 299 792 458 m / s. So where is the error?
A little my reasoning. In my personal opinion, the presence of electric charges is not conditioned. It all started with the experience put by Robert Andrews Millikan in conjunction with Harvey Fletcher in 1909. I have not found the information anywhere, but rather it does not exist, who interpreted the results of the experiment so. According Robert Andrews Millikan's results, determine the minimum multiplicity of the electric charge. But he did not determine the charge itself - it's simply impossible. But over time, someone decided that if there is a value, then there must be a material provision of this magnitude. In my opinion, this property is that it can also have a value. There is a very important argument in favor of this. No one has ever been able to get a single charge. All charges exist only in pairs. And this says more about the property of matter, the view of which is carried out from different and opposite sides, than on the presence of separate electric charges. We call it plus and minus. And secondly you never get an electric charge separately from the substance. This property is possessed only by matter. In this regard, I like the concept introduced by Michael Faraday - this is an electrical displacement. It very accurately determines the nature of electricity.
