Electron
Electron (Greek Ηλεκτρόνιο) is an elementary particle carrying a negative electric charge. It is one of the fundamental constituents of atoms, alongside protons and neutrons.

Atom
The atom is the basic unit of matter, consisting of a nucleus of protons and neutrons, surrounded by electrons that orbit the nucleus in shells or energy levels.
Superconductor
Superconductor is a material that at very low temperatures (close to absolute zero) has zero electrical resistance and allows electric current to flow without any energy loss. The most well-known superconductor is mercury, which has zero resistance at a temperature of 4.2 K (-268.8 °C). However, due to the instability and toxicity of mercury, its …
Diamagnetics
Diamagnetics are materials or substances that do not possess permanent magnetic properties and repel external magnetic fields. Diamagnetism is one of the three main forms of magnetism, along with ferromagnetism and paramagnetism.

Law of conservation of electric charge
The Law of Conservation of Electric Charge states that electric charge cannot be created or destroyed; it can only be transferred from one body to another.
Renewable energy sources
Renewable energy sources are sources of energy that can be continuously used and do not get depleted through utilization.
Current density
Current density is a vector physical quantity equal to the ratio of the electric current passing through an elementary surface located perpendicular to the direction of charge movement to its area.
Faraday’s Law
Faraday’s Law is a fundamental law of electromagnetism that describes the interaction between electricity and magnetism. The law was discovered by Michael Faraday in 1831.
Types of Power Plants
Types of Power Plants. Depending on the source of energy, the following types of power plants are distinguished: Thermal power plants, hydroelectric power plants, nuclear power plants, unconventional power plants. An electric power station is a complex of installations, equipment, and apparatus used directly for the production of electrical energy, as well as the necessary …
