  1. Exploring Electrical Technology Advances in the Age of Electricity: Faraday’s Foundation leads to Communications Transformed by the Telegraph

  2. Highlights of Faraday’s Career • Demonstrated electricity could produce mechanical motion (1821) • Davy’s death in 1829 leads to more freedom

  3. Highlights of Faraday’s Career • Most productive years • 1831 demonstrated mechanical motion to electrical energy conversion (em induction) • 1832: identified electricity from various sources • 1833: worked on electrolytic decompositions • Later years • 1836 studied electrostatics: Faraday cage • 1845 related light, electricity and magnetism • 1846-1862 other discoveries

  4. Faraday versus Franklin • Education • Work with books • Number of inventions / areas • Commitment to observation/experiment • Morality and interest in common good • Attitude toward patents • Royal Society Membership • Weakness in mathematics

  5. Inventions by Faraday’s Contemporaries • The Telegraph: early forms • 1831 Wheatstone & Fathergill (English) • Created the 1st telegraph machine • Note the large battery

  6. The Telegraph: Early Forms • 1833 Gauss & Weber (Germans) • 1835 Joseph Henry (American)

  7. The Telegraph takes off www.eham.net/articles/7527 • Samuel Finley Breese Morse • Patented his version (1837) that sent letter codes of dots and dashes • Sent his famous message from Washington to Baltimore (1844) •          /            / •         / •                     /      

  8. The Telegraph improves http://www.thocp.net/biographies/bain_alexander.htm • Alexander Bain (1846): • 1854 Electric telegraph installed between Paris and London (European feat)

  9. The Telegraph extended • 1861 New York & San Francisco connected by a telegraph line (American feat) • 1866 Cyrus West Field layed a telegraph cable across the Atlantic Ocean (joining the European & American continents)

  10. Development of Voltage Sources • 1832 Hyppolyte Pixii demonstrated a hand driven “magneto-electric machine” • 1834 Clark produced a commercial electromagnetic generator

  11. Development of Voltage Sources • 1859 Gaston Plante invented the storage battery • 1867 Zenobe Theophile Gramme built the 1st commercially practical generator for producing AC

  12. How Transmission Cables Work • The answer lies in the difference between insulated wire versus insulated cable
