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 charge of one coulomb through an electrical potential difference of one volt. The work done to produce the power of one watt continuously for one second.
