ETYM From the distinguished English physicist, James P. Joule.
(Homonym: jewel).
A unit of electrical energy equal to the work done when a current of one ampere passes through a resistance of one ohm for one second; SYN. J, watt second.
SI unit of energy (or work or heat) equal to one newton-meter.
Unit of energy or work: equal to work done when force of one newton moves its point of application one meter.
SI unit (symbol J) of work and energy, replacing the calorie (one joule equals 4.2 calories).
It is defined as the work done (energy transferred) by a force of one newton acting over one meter and equal to 107 ergs. It can also be expressed as the work done in one second by a current of one ampere at a potential difference of one volt. One watt is equal to one joule per second. + prikaži više
