Stephen Gray experiments with static electricity, proving to an audience that the human body conducts electricity

The Leyden jar is invented - it stores static electricity charges so they can be used whenever

Jean Desaguliers makes a discovery, that electric current flows freely through some materials (conductors) and not others (insulators)

Alessandro Volta makes the first electric cell named a "voltaic pile" and invents the phrase "electric current"

Humphry Davy used a voltaic pile for his electrolysis experiments, to create the strongest battery yet

Professor Hans Oersted wanted to prove to students that there was no connection between magnetism and electricity. He held an electric wire over a magnetic needle and the compass moved, proving they are in fact related

Michael Faraday repeats Oersted's experiment, but instead changes it, finding an efficient way to create electrical current

Joseph Henry builds the largest and strongest magent known to date, the giant electro-magent can lift more than 1 ton of iron

James Mexwell states that light consists in the transverse undulations of the same medium which is the cause of electric and megnetic phenomena

Faraday puts his thoughts together and invents a giant electric generator - a dynamo - which is a source of cheap electirc current. He then creates the first electrical transformer and electric motor
