Who invented Ohm's law?

Ohm's law was discovered and named by Georg Simon Ohm, a German physicist, in the 1820s. The discovery was published in his pamphlet, "The Galvanic Circuit Investigated Mathematically," in 1827.

The equation "I = V/R" is known as Ohm's law. It states that the amount of steady current, I, through a material is directly proportional to the voltage, V, across the material, divided by the electrical resistance, R, of said material. When Ohm first published his findings, they were so coldly received that he resigned from his position in Cologne and took up a new teaching position in Nürnberg in 1833. His work was finally recognized in 1841, and he was awarded the Copley Medal of the Royal Society of London.
