James Prescott Joule (December 24, 1818 – October 11, 1889) was an English physicist, born in Salford, near Manchester. In his time he had great contribution to the world of electricity and thermodynamics. He was best known for creating Joules law, which described electric heating by saying the amount of heat produced each second in a conductor by a current of ELECTRICITY is proportional to the resistance of a conductor and to the square of the current. The unit for this is Joule was equaled to 1 Watt-second. Later Joule worked with William Thomson to find out that the temperature of gas falls, as gas expands. This principle was then know as the Joule-Thomson effect.
