Joule-heating or resistive-heating is used in multiple devices and industrial process. The part that converts electricity into heat is called a heating element. Among the many practical uses are: • An incandescent light bulb glows when the filament is heated by Joule heating, due to thermal radiation (also called blackbody radiation). Nettetjoule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds. In electrical terms, the joule equals one watt-second—i.e., the energy released in one …
