Electricity is a stream of particles moving in a certain direction. They have some charge. In another way, electricity is the energy that is obtained during movement, as well as the lighting that appears after energy is received. The term was coined by William Gilbert in 1600. When conducting 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…
Due to electricity, an electric field is created around current conductors or bodies with a charge. Through it, it becomes possible to influence other bodies, which also have a certain charge.
Everyone knows that there are positive and negative charges. Of course, this is a conditional division, but according to the current history, they continue to be designated as such.
If the bodies are charged the same way, they will repel, and if differently charged, they will attract.
The essence of electricity is not only the creation of an electric field. There is also a magnetic field. Therefore, betweenthey have a relationship.
More than a century later, in 1729, Stephen Gray established that there are bodies that have very high resistance. They are capable of conducting electricity.
Currently, thermodynamics is most concerned with electricity. But the 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, to this day, research continues, new properties are revealed. But in the science we are taught in school, there are several names.
It is believed that the first who became interested in electricity was the philosopher Thales, who lived in Ancient Greece. It was he who rubbed the amber against the wool and watched as the bodies began to be attracted.
Aristotle then studied eels, which struck enemies with what was later understood to be electricity.
Later Pliny wrote about the electrical properties of resin.
A number of interesting discoveries were assigned to the physician of the English Queen, William Gilbert.
In the middle of the seventeenth century, after the term "electricity" became known, Mayor Otto von Guericke invented the electrostatic machine.
In the eighteenth century, Franklin created a whole theory of the phenomenon, saying that electricity is a fluid or immaterial liquid.
Besides the people mentioned, famous names such as:
- Pendant;
- Galvani;
- Volt;
- Faraday;
- Maxwell;
- Amp;
- Lodygin;
- Edison;
- Hertz;
- Thomson;
- Claude.
Despite their undeniable contribution, Nikola Tesla is rightfully recognized as the most powerful scientist in the world.
Nikola Tesla
The scientist was born in the family of a Serbian Orthodox priest in what is now Croatia. At the age of six, the boy discovered a miraculous phenomenon when playing with a black cat: her back suddenly lit up with a strip of blue, which was accompanied by sparks when touched. So the boy first learned what "electricity" is. This determined his whole future life.
Scientist owns inventions and scientific papers about:
- AC;
- on air;
- resonance;
- field theory;
- radio and more.
Many associate the event, called the Tunguska meteorite, with the name of Nikola Tesla, believing that a huge explosion in Siberia was not caused by a fall of a cosmic body, but by an experiment conducted by a 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 amino acids began to be synthesized, which means that life appeared. It has been established that movements, breathing and other processes occurring in the body arise from a nerve impulse, which is of an electrical nature.
The well-known fish -electric stingrays - 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 create energy that is transmitted through special lines. Current is generated by converting internal or mechanical energy into electrical energy. Stations that produce it, where electricity is connected or disconnected, are of various types. Among them are:
- wind;
- sunny;
- tidal;
- hydroelectric power plants;
- thermal atomic and others.
Electricity connection today occurs almost everywhere. Modern man cannot imagine life without it. With the help of electricity, lighting is produced, information is transmitted by telephone, radio, television … Due to it, transport such as trams, trolleybuses, electric trains, metro trains functions. Electric vehicles are emerging and asserting themselves more and more.
If there is a power outage in the house, then a person often becomes helpless in various matters, since even household appliances work with the help of this energy.
Tesla's Unsolved Mysteries
The properties of the phenomenon have been studied since ancient times. Mankind has learned how to conduct electricity using various sources. It made their life much easier. Nevertheless, in the future, people still have a lot of discoveries related to electricity.
Somesome of them may even have already been made famous by Nikola Tesla, but then were classified or destroyed by himself. Biographers claim that at the end of his life, the scientist himself burned most of the records, realizing that humanity was not ready for them and could harm itself by using his discoveries as the most powerful weapon.
But according to another version, it is believed that some of the records were seized by US intelligence agencies. History knows the US Navy destroyer Eldridge, which not only had the ability to be invisible to radar, but also moved instantly in space. There is evidence of an experiment, after which part of the crew then died, the other 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. This means that humanity is not yet morally ready for this.
