The History of Electronics The men that came up with all those formulas, theories and laws we have to know! History of Electronics Ancient Rome had batteries (Did they know what they were doing?) Ancient Greece developed a knowledge of ‘Steam power’ (didn’t want to get their hands dirty!) Understanding started later When should we start? Electricity Dozens of people Responsible Research took several hundred years Most theories/information developed by 1900 Electronics Many individuals contributed Electrical experiments and information built the ‘base’ for Electronics Associated with Wireless developments Generally regarded as ‘starting’ about 1900 William Gilbert 1544-1603 Wrote De magnete Researched Magnetics Static Electricity Distinguished between Magnetism and static electricity Leyden Jar Was the first Capacitor Developed by Pieter van Musscenbroech Benjamin Franklin 1706-1790 Writer and Scientist Researched Electricity Researched Weather Meteorology Defined Positive Negative Charges Had many other inventions! Charles Coulomb 1736-1806 Experimented in mechanical resistance Developed Coulomb’s Law for electrostatic charges Luigi Galvani 1737-1798 Studied effects of electricity on Frogs! Revealed animals had and were effected by electricity. Alessandro Volta 1745-1827 Very Interested in Electrical experiments going on in late 1700’s Invented the battery Hans Christian Oersted 1777-1851 Demonstrated that electricity effected magnetism Ini
