James Prescott Joule

James Prescott Joule (English; 24 December 1818 – 11 October 1889) Physicist who studied the nature of heat and its relationship to mechanical work. He worked with Lord Kelvin to develop the absolute scale of temperature, and found the relationship between the flow of current through a resistance and the resulting heat dissipated – this is now called “Joule’s law”. The “joule” which is named after him is a unit of work with several definitions: The work done, or energy required, to exert a force of one newton for a distance of one meter. The work required to move an electric … More
