Vem var det som kom på Elektriciteten, alltså det vi använder till våra datorer osv :)? Jag gissade på Michael Faraday men det verkar fel :O!

Well, no one really "invented" electricity, but you can ask who discovered it. While people have known about the powerful effects of lightning for thousands of years, the first person to discover that lightning was a naturally occuring form of electricity was Benjamin Franklin. In 1752, during a dangerous electrical storm, Franklin flew a kite that had a metal key at the bottom of the string. When a bolt of lightning hit the kite, a spark of electricity flew from the key! From this experiment, Franklin invented the lightning rod, which attracts lightning and draws it into the ground. This saves many buildings from burning down.

No-one made electricity because it was always there in lightning

600 B.C. Thales of Miletus writes about amber becoming charged by rubbing - he was describing what we now call static electricity.
1600 A.C. English scientist, William Gilbert first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification of many substances in his "De magnete, magneticisique corporibus". He also first used the terms electric force, magnetic pole, and electric attraction.
1660 A.C. Otto von Guericke invented a machine that produced static electricity.
1747 A.C. Benjamin Franklin experiments with static charges in the air and theorized about the existence of an electrical fluid that could be composed of particles. William Watson discharged a Leyden jar through a circuit, that began the comprehension of current and circuit. Henry Cavendish started measuring the conductivity of different materials
1752 A.C. Benjamin Franklin invented the lightning rod - he demonstrated lightning was electricity.
1786 A.C. Italian physician, Luigi Galvani demonstrated what we now understand to be the electrical basis of nerve impulses when he made frog muscles twitch by jolting them with a spark from an electrostatic machine.
1821 A.C First electric motor (Faraday).

Man tackar! :D kom på att jag kunde kolla på wikipedia nu men tack :)

Dom som inte orkar söka själv brukar ju använda Kolozzeum så
