Today, hard to imagine the actual daily work and residence life without electricity. Electricity is accompanied by the man from the very beginning, even in the type of atmospheric phenomena and biological processes in your body, but it took a while before man began to utilize its current activities.

As the first phenomenon of electricity begun to explore the ancient Greeks as well as Egyptians. They found, for example, that rubbing amber will certainly attract individual blades connected with grass. Modern archaeologists, on the basis connected with his excavations, said that Egyptian priests could actually perform simple primary cellular material. Similar devices were obtained in Asia Minor, and their age is dependent upon surowce chemiczne about 4500 years.

Over the next century, researchers have generally not at all engaged in electricity, until the sixteenth century AD. It was then of which, thanks to the British physician William Gilbert, appeared in the term “electricity”. This doctor took the analysis initiated by the ancient Greeks, and after many experiments he learned that not only amber, after rubbing, it attracts other figures.

Similar experiments led other scientists. Girolamo Cardano noticed that the static electricity and magnetism, despite a similar effect, however, are quite different phenomena. Shortly after Stephen Grey has demonstrated that electric charges can move through moist conductors and precious metals. “Liquidity” cargo was not the one discovery also introduced the thought of positive and negative electrons.

In the eighteenth century, Benjamin Franklin made the experiment with a kite during any storm, whose aim was to be able to prove that lightning is often a powerful electric discharge. The result of his work is bluzki applied to the electrical charge conservation principle plus the principle of electrostatic induction. Another researcher electricity, Joseph Priestley, described the effect connected with distance between two physical objects, which attract each other intoxicated by static electricity.

Scientific proof of that thesis carried Charles Coulomb. His calculations showed that the forces acting between the actual charges are directly proportional to the product of their expenses and inversely proportional to the square of the cheap home insurance range between them.

The first chemical cell consisting of gold and silver plates separated paper Alessandro Volta created. Volta is a heir of Georg Ohm, among others, Gustav Kirchhof, James Maxwell, the authors of the most crucial laws of electrodynamics.
