HISTORY OF ELECTRICITY
PIONEERS 1600 - 1900
Thales of Miletus (630-550 BC) was the first, about 600 BC, knew that amber, when rubbed acquires the power of attraction on some objects.
But the Greek philosopher Theophrastus was (374-287 BC) the first, in a written three centuries later, established that other substances have the same power, thus demonstrating the first scientific study onelectricity.
In 1600
Queen Elizabeth I ordered the actual physical William Gilbert (1544-1603) study of magnets to improve the accuracy of compasses used in navigation, this work being the primary basis for defining the fundamentals of Electrostatics and Magnetism.
Gilbert was the first to apply the term electricity from the Greek "elektron" = amber.
Gilbert is the unit of measurementof magnetomotive force.
Compass, 1562
In 1672
The German physicist Otto von Guericke (1602-1686) developed the first electrostatic machine to produce electrical charges.
Machine consisting of a sulfur sphere turning, with a handle through which the charge is induced to place my hand on the dial.
Guericke
In 1733
The Frenchman Francois Du Fay Cisternay (14/Sep/1698 - 1739) wasthe first to identify the existence of two electric charges, which called resinous electricity and Vitria:
Positive and Negative.
In 1745
It develops that would lead to the capacitor, the Leyden jar by E. G. Von Kleist (1700-1748) and Pieter Van Musschenbroeck (1692-1761) at the University of Leyden, this bottle was stored static electricity.
MusschenbroeckBotella Leyden
In 1752Benjamin Franklin (1706-1790) demonstrated the electrical nature of lightning.
He developed the theory that electricity is a fluid that exists in this area and its flow is due to excess or defect of it in her. Invented the lightning rod.
In 1780 he invented bifocals.
Franklin
In 1766
The Chemist Joseph Priestley (1733-1804) proves that the force exerted between electric chargesvaries inversely proportional to the distance between them.
Priestley showed that electric charge is distributed evenly on the surface of a hollow sphere, and inside it, there is no electric field, or an electric force.
Priestley discovered oxygen.
Priestley
In 1776
Charles Augustin de Coulomb (1736-1806) invented the torsion balance with which, accurately measured the force betweenelectric charges and confirmed that the force was proportional to the product of the individual charges and inversely proportional to the square of the distance that separates.
Coulomb is the unit of measurement of electrical charge.
In 1800
Alessandro Volta (1745-1827) built the first battery cell Electrostatics and capable of producing electricity. His inspiration came from the study bythe Italian physicist Luigi Galvani (1737-1798) on nerve-electric currents in frog legs.
Galvani proposed the theory of animal electricity, which resented by Volta, who believed that muscle contractions were the result of contact of two metals with the muscle.
His subsequent research led him to develop a chemical cell capable of producing direct current, as well as development was the battery.Volt is the unit of measure of electrical potential (voltage).
From 1801 to 1815
Sir Humphry Davy (1778-1829) developed the electrochemical (named by himself), exploring the use of the voltaic pile or battery, and trying to understand how it works.
In 1801 he observed the arc and glow with an energized conductor in a battery.
Between 1806 and 1808 published the results of theirresearch on electrolysis, which achieves the separation of magnesium, barium, strontium, calcium, sodium, potassium and boron.
In 1807 he produced a stack of over 2000 double plates, with which it discovers and shows that chlorine is an element, rather than an acid.
In 1815 he invented the safety lamp for miners.
Without any doubt, the most important discovery I made that same year, when...
