James Prescott Joule
James Prescott Joule, (born December 24, 1818, Salford, Lancashire [now in Greater Manchester], England—died October 11, 1889, Sale, Cheshire), English physicist who established that the various forms of energy—mechanical, electrical, and heat—are basically the same and can be changed one into another.James Prescott Joule experimented with engines, electricity and heat throughout his life. Joule's findings resulted in his development of the mechanical theory of heat and Joule's law, which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit.
