Examples and problems with solutions are given.

For students of secondary vocational education of electric power and electrical engineering specialties.
Electricity. Electrical conductivity.
All substances are made up of atoms. The atom contains a nucleus around which electrons with a negative charge revolve. In the nucleus of an atom, protons with a positive charge and electrically neutral neutrons are concentrated. Figure 2.1 shows a simplified model of the hydrogen atom.
If the number of electrons is equal to the number of protons in the nucleus, then the atom is electrically neutral. If an atom loses one or more electrons, it acquires positive polarity and becomes an ion. But if an atom attaches one or more electrons, then it becomes a negative ion.
For an electric current to occur, three conditions must be met:
1) the presence of free charge carriers (electrons in metals, ions in electrolytes);
2) the presence of an electric field in the conductor;
3) the presence of a closed circuit.
To understand how an electric current flows through wires, let's recall the electronic theory of the structure of metals: positively charged ions vibrate near the nodes of the crystal lattice of the metal. Between them in chaotic motion, electrons seem to float, forming an "electron gas".
When a conductor is connected to a source of electrical energy, the electrons move in order, and an electric current is generated. We cannot directly observe the electric current. The passage of a current is judged by its effect - thermal, magnetic and chemical.
