The essence of electricity. Electricity is ...

Electricity is a flow of particles moving in a certain direction. They have a certain charge. In another way, electricity is the energy that is produced by movement, as well as the lighting that appears after receiving energy. The term was introduced by scholar William Gilbert in 1600. In carrying out experiments with amber, the ancient Greek Thales discovered that a charge was acquired by the mineral. "Amber" in Greek means "electron". Hence the name.

Electricity is ...

Thanks to electricity, an electric field is created around conductors of current or bodies with charge. Through it, it becomes possible to work on other bodies, which also have a certain charge.

Everyone knows that charges are positive and negative. Of course, this is a conditional division, but according to the existing history, they continue to be labeled.

If the bodies are charged equally, they will be repelled, and if differently - attracted.

The essence of electricity is not only the creation of an electric field. There is also a magnetic field. Therefore, there is a relationship between them.

More than a century later, in 1729, Stephen Gray established that there are bodies that have very much resistance. They are capable of conducting electric current.

Currently, most of all, electricity is handled by thermodynamics. But quantum properties of electromagnetism are studied by quantum thermodynamics.

History

It is hardly possible to name a specific person who discovered the phenomenon. After all, research continues to this day, new properties are emerging. But in the science that we are taught in school, several names are called.

It is believed that the first person interested in electricity was the philosopher Thales, who lived in Ancient Greece. It was he who rubbed amber on his wool and watched the bodies begin to attract.

Then Aristotle studied the eels that hit the enemies, as they later realized, by electricity.

Later, Pliny wrote about the electrical properties of resin.

A number of interesting discoveries consolidated the doctor of the English queen, William Gilbert.

In the middle of the seventeenth century, after the term "electricity" became known, the burgomaster Otto von Guericke invented an electrostatic machine.

In the eighteenth century, Franklin created a whole theory of the phenomenon, which says that electricity is a fluid or an immaterial fluid.

In addition to the people mentioned, this question is connected with such famous names as:

• Pendant;
• Galvani;
• Volt;
• Faraday;
• Maxwell;
• Ampere;
• Lodygin;
• Edison;
• Hertz;
• Thomson;
• Claude.

Despite their undeniable contribution, the most powerful of scientists in the world is rightly recognized as Nicolas Tesla.

Nikola Tesla

The scientist was born into the family of a Serbian Orthodox priest in the territory of present-day Croatia. At six years old the boy discovered a wonderful phenomenon when he was playing with a black cat: her back suddenly lit up with a strip of blue color, which was accompanied by sparks when touched. So the boy first learned what "electricity" is. This determined his entire future life.

The scientist owns inventions and scientific works on:

• Alternating current;
• Ether;
• Resonance;
• Field theory;
• Radio and much more.

Many associate the event, which was called the Tunguska meteorite, with the name of Nikola Tesla, considering that the huge explosion in Siberia was caused not by the fall of the cosmic body, but by the experience conducted by the scientist.

Natural electricity

At one time in scientific circles there was an opinion that electricity does not exist in nature. But this version was refuted when Franklin established the electrical nature of lightning.

It was thanks to her that the amino acids began to be synthesized, which means that life appeared. It is established that the movements, breathing and other processes occurring in the body arise from a nerve impulse that is of an electrical nature.

All known fish - electric rays - and some other species are protected in this way, on the one hand, and hit the victim, on the other.

Application

Electricity is connected by generators. Power plants generate energy transmitted through special lines. The current is formed due to the transformation of internal or mechanical energy into electrical energy . The stations that produce it, where electricity is connected or disconnected, come in various forms. Among them are:

• Wind;
• Solar;
• Tidal;
• Hydroelectric power stations;
• Thermal atomic and others.

Electricity connection today occurs almost everywhere. Imagine a life without him a modern man can not. With the help of electricity, lighting is carried out, information is transmitted over the telephone, radio, television ... Due to it, there is such transport as trams, trolleybuses, electric trains, subway trains. There are also more and more boldly declaring themselves electromobiles.

If there is a power outage in the house, then the person often becomes helpless in different matters, since even household appliances work with the help of this energy.

Unsolved secrets of Tesla

Properties of the phenomenon have been studied since ancient times. Mankind has learned how to conduct electricity using various sources. This greatly facilitated their lives. Nevertheless, in the future, people still have a lot of discoveries related to electricity.

Some of them may even have already been made famous by Nikola Tesla, but then they were classified or destroyed by him. Biographers say that at the end of life most of the records the scientist burned with his own hands, realizing that humanity is not ready for them and can harm themselves, using its discoveries as the most powerful weapon.

But according to another version, it is believed that some of the records were seized by US special services. The US destroyer "Eldridge" is known for its history, which not only had the ability to be invisible to radars, but also moved instantly in space. There is evidence of an experiment, after which part of the crew then perished, another part disappeared, and the survivors went crazy.

One way or another, it is clear that all the secrets of electricity have not yet been revealed. Hence, humanity is morally not yet ready for this.
