Ohm


Ohm
   , OHM'S LAW
   Georg Simon Ohm (1787-1854), was born in Erlangen, Bavaria, Germany, to a family of locksmiths.
   Ohm received a doctorate in physics when he was twenty-two and then accepted a position teaching mathematics at the Jesuit college in Cologne. He was not well accepted by his fellow scientists, which caused him to resign. To obtain another teaching assignment, Ohm sent a copy of a book he had written to the monarchs of the various German states. His strategy paid off. The king of Prussia invited him to teach at the Royal Konsistorium in Cologne. His research at that institution led him to discover the basic law of electrical resistance.
   The International Electrical Congress voted at its meeting in Chicago in 1893—thirty-nine years after Ohm's death—to adopt his name for a unit of electrical resistance. Ohm's Law is set forth as "current equals volts divided by ohms."
