Georg Ohm

1789–1854 · Physics

Georg Simon Ohm was a German physicist and mathematician. Working as a school teacher with equipment he built himself, he experimented with the electrochemical cell invented by Alessandro Volta and found that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance. This relationship, now written V = IR and known as Ohm's law, was published in 1827 in his book Die galvanische Kette, mathematisch bearbeitet. His heavy reliance on mathematics was coldly received at first, but his work was later recognised with the Royal Society's Copley Medal in 1841, and the ohm, the unit of electrical resistance, is named in his honour. Ohm's law is the basis for the electricity calculators in this section.
