What is an electric generator?

What is an electric generator?

An electric generator is a machine able to transform any type of energy, which can be chemical, mechanical or light, into electricity.

An electrical generator is all that a device capable of maintaining electric potential difference (voltage) between two points, called centers or terminals. Electric power generators are machines designed to transform mechanical energy into electricity.

Operation of an electric generator

The operation of an electric generator is similar to an electric motor running in reverse.

This transformation is achieved by the action of a magnetic field on electrical conductors arranged in coils on armor plates. If mechanically relative movement…

Chinon Nuclear Power Plant

Chinon Nuclear Power Plant

The Chinon nuclear power plant is located in France, near Chinon in the territory of the city of Avoine (Indre-et-Loire) in the Country of Véron. Uses water from the Loire River.

The annual production of the nuclear plant is approximately 24 billion kilowatt-hours per year. This production accounts for approximately 4% of national electricity production in France. 1500 people work in the nuclear power plant.

History of the Chinon nuclear power plant

The Chinon nuclear power plant has two different types of nuclear reactors:

Gas-graphite reactors

Between July 1955 Electricité de France (EDF) controls a nuclear reactor project at the Commissariat for Atomic…

Radioactivity definition

Radioactivity definition

Radioactivity defined as the spontaneous emission of particles (alpha, beta, neutron) or radiation (gamma, K capture), or both at the same time, from the decay of certain nuclides that these particles are, due to an adjustment of their internal structure.

Radioactivity can be natural or artificial. In natural radioactivity, the substance already has radioactivity in the natural state. In artificial radioactivity, the radioactivity has been induced by irradiation.

A radionuclide is all the radioactive cores of the same kind. All radioactive cores forming a radionuclide have a well-defined radioactivity, which is common to all of them and that identifies them; the…

Cattenom I Nuclear Power Plant

Cattenom I Nuclear Power Plant

The Cattenom Nuclear Power Plant is a nuclear power plant located in France. It is currently operated by Electricité de France (EDF). Geographically it is located in Lorraine, in the town of Cattenom, on the Moselle banks between Thionville and Trier. The cities of Luxembourg, Arlon, and Metz are very close to the nuclear power plant.

Luxembourg, Saarland and Belgium demanded closure of the plant. In spite of this, there is a project under way to extend its useful life until 2025.

Characteristics of the Cattenom nuclear power plant

The Cattenom nuclear plant is a nuclear fission power generation facility. It has four nuclear water pressure reactors (PWR). Each of these…

Definition of energy

Definition of energy

Ability of a physical system to produce a job.

This definition, although it is the most widespread, can be misleading because of the vagueness of the term "capacity", and therefore, it is better to define the energy as what, when a work occurs, decreases in an amount equal to the work produced. Energy, then, is measured in the same units as labor.

History of the study of energy

The notion of energy appears for the first time from the investigations of Joule and Carnot on the conversion of heat in mechanical work and thanks to the theory of Helmholtz in which it connects the work done by an isothermal system with the internal energy and the Entropy of this system. In this…

Chemical energy

Chemical energy

Chemical energy is the potential of a chemical to undergo a transformation through a chemical reaction or to transform into other chemicals. Forming or breaking chemical bonds involves energy. This energy can be absorbed or evolved from a chemical system.

The energy that can be released (or absorbed) by a reaction between a set of chemical substances is equal to the difference between the amount of energy of the products and the reactants. This change in energy is called the internal energy of a chemical reaction.

The internal energy change of a process is equal to the change of heat if it is measured under constant volume conditions, as in a calorimeter. However under conditions…

Electric power. What is it?

Electric power. What is it?

We define electrical energy as the form of energy that results from the existence of a potential difference between two points. When these two points are brought into contact by an electric conductor we obtain an electric current.

Physical aspects of electrical energy

From a physical point of view, electrical energy is negative electrical charges (electrons) that move through the electric conductor, usually metallic, due to the potential difference between its ends. The reason metal conductors are usually used is because they have more free electrons.

Electric charges moving through the conductor are part of the atoms of the conductor's own substances.

In physics…

Heat energy definition

Heat energy definition

Heat energy is the manifestation of the energy in the form of heat. All materials have atoms that form molecules with constant movement and vibration. This movement of atoms generates a kinetic energy called heat or heat energy.

If we increase the temperature of any element, we increase its heat energy. However, when we increase the heat energy of an element it's not guarantee that its temperature is increased. The temperature is the same during the stage of changes. A good example is heating some water. Little by little we obtain heat energy and the temperature increases. However, when it reaches 100 °C (boiling temperature) the…

What is a proton? Definition

What is a proton? Definition

A proton is a subatomic particle with a positive electric charge that lies within the atomic nucleus of atoms. The number of protons in the atomic nucleus is that which determines the atomic number of an element, as indicated in the periodic table of the elements.

The proton has +1 charge (or, alternatively, 1,602 x 10-19 coulombs), exactly the opposite of the charge -1 containing the electron. In mass, however, there is no competition because the mass of the proton is approximately 1,836 times greater than that of an electron.

The proton is classified as a baryon, and is composed of three quarks (uud). The corresponding antiparticle, the antiproton, has the same…

Definition of neutron

Definition of neutron

A neutron is a subatomic particle contained in the atomic nucleus. It has no net electric charge, unlike the proton that has a positive electric charge. The number of neutrons in the atomic nucleus of an element determines the isotope to which it is a part.

Discovery of the neutron

The first clue to the existence of the neutron occurred in 1930, when Walther Bothe and Becker, H. found that when alpha radiation fell on elements such as lithium and boron, a new form of radiation was emitted.

Initially, this radiation was believed to be a type of gamma radiation, but it was more penetrating than any known gamma radiation. The work done by Irene Joliot-Curie and Joliot Frederic…

Applications of nuclear technology

Applications of nuclear technology

The main use of nuclear energy is the production of electric energy. Nuclear power plants are responsible for generating electricity. Nuclear fission reactors are generated in the nuclear reactors of the nuclear power plants. With these reactions thermal energy is obtained which will be transformed into mechanical energy and later into electrical energy.

However, there are many other applications where nuclear technology is used directly or indirectly.

Working with different isotopes of the same element, nuclear technology can be used for other applications in various fields:
