Physics was next to true    The current of free electrons is considered to be the conduction current in the modern theory of electricity. And the theory of alternating current is based on the assumption that electrons can change the direction of their motion in the opposite direction. In addition, in the modern theory of electricity, it was believed that Coulomb forces act only between charges. In fact, a metal conductor with a zero charge acts in metal conductors. And it is this conductor with a zero charge that is the central element of electricity, without which no current will run anywhere because the difference in electric potentials between a conductor with a zero charge and the negative (or positive) charge of the current source  to  to gives birth of movement of the charges - EMF. These errors of the modern theory of electricity are connected with the fact that only now physical science, and first of all, quantum physics, began to clarify the nature of the charges of electrons and positrons. It turned out that there are no specific electric charges in nature, because an electron - by 2/3 of its volume - is a magnetic dipole of the north pole, called a minus, and a positron is a magnetic dipole of the south pole, called a plus. Each charge generates 1/3 of the volume of the magnetic induction of the opposite pole. Moreover, a larger magnetic charge is considered an electric charge, and a smaller magnetic charge is considered to be the magnetic component of the charges, which, when current flows in the conductor, generates speraloid lines of magnetic induction. Clarification of the nature of the charges of electrons and positrons allows us to clarify the question of what the devices show, which should show the sign of the charge of the particles forming the current, the direction of their movement and the strength of the current. A device that is capable of showing all of the named current parameters is a magnetoelectric galvanometer. The main element tha ... Read more
