What is an electrostatic generator?

The electrostatic generator is a device that generates a high voltage by a gradual accumulation of charges via a low -energy current, which can then be stored for later use. These devices convert a mechanical effect into an electric charge and create what is called static electricity, such as the one that has been generated when you cuddle your cat or encounter a balloon, but in much larger quantities. The first electrostatic generator is considered to be invented by Otto von Guericke at the end of the 17th century.

devices of this type generally fall into two categories: tribelectric or friction machines and electrostatic induction machines. Both machine types generate the same type of electric current, but in different ways. The first electrostatic generator was the friction machine, but later improved improved machines type electrostatically induction.

Electrostatic types of friction type rely on tribelectric effect, which is a generation of SMALL electric current when JSou two materials wiped against each other. The first machine had a rotating globe of sulfur, which collected an electrostatic charge by wiping his hand about him when he turned. Later research has shown that other materials such as glass can be used.

Electrostatic induction machines, also called influential machines, work on the principle of induction charge. Through this process, the charged object can hand over the opposite charge to another object simply by placing near the second object. This process is associated with a certain type of mechanical operation, such as a rotating disc disc, so that charging is constantly adding to a storage object.

The

Van de Graff generator is an advanced electrostatic induction generator. Some of the largest electrostatic generators can create hubs of up to 10 million volts. The first -mentioned scientist MIT in 1929 is this type of electrostatic generator the most famous, which withHe has discovered in many films and TV shows as a popular part in the laboratories of "Mad Scientist". However, these devices have great legitimate scientific value.

Machines as a Van de Graff generator and other electrostatic generators are common in teaching and demonstration environments such as physical laboratories or museums. They are usually used to demonstrate the properties of static electricity and phenomena associated with high electricity. They also found use in X -ray tubes and other medical applications, as well as in the research of physics, industry and food processing.
