Stephen Gray - discovered that some substances conduct electricity and some not.

Charles du Fay - discovers vitreous and resinous electricity,he found that object with vitreous electricity repeled each other and object with resinous electricity attracted each each other.

Benjamin Franklin - theorized that elektricoty consisted of a single fluid , first used terms positive and negative, showed that lighting is eletricity.

Charles Augustin de Coulomb - French physicist, laws govern the attraction and repulsion between electrically charged bodies.

Luigi Galvani - experimented with current elektricity, profesor of anatomy at the University of Bolognia in Italy.

Alessandro Volta - Italian professor of physics, discovered the chemical action between moisture and two differerent metals produced elektricity.

Andre Ampere - measured rhe magnetic effect of an electrical current, he found that two wires carrying current can attract and repel each other.

George Simon Ohm - formulated one of the most used laws in electrical circuits (Ohms law - gives relationship among resistance, voltage, current)

Michael Faraday - he found that if elektricity could produce magnetic effect, then magnetism could produce elektricity. He discovered electromagnetic induction.

James Clerk Maxwell - produced mathematical equations expressed the laws govering elektricity and magnetism.

Heirich Rudolf Hertz - unit of frequency called Hertz

vacuum tube was used to detect elektromagnetic waves.
