Random House Webster's College Dictionary
the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force.
Ref: Abbr.: J 4 2 , j 4 2
Origin of joule:
1885–90; after J. P. Joule
James Prescott, 1818–89, English physicist.
joule, J, watt second(noun)
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
Joule, James Prescott Joule(noun)
English physicist who established the mechanical theory of heat and discovered the first law of thermodynamics (1818-1889)
In the International System of Units, the derived unit of energy, work and heat; the work required to exert a force of one newton for a distance of one metre. Also equal to the energy of one watt of power for a duration of one second. Symbol: J
Origin: Named after the English physicist James Prescott Joule.
a unit of work which is equal to 107 units of work in the C. G. S. system of units (ergs), and is practically equivalent to the energy expended in one second by an electric current of one ampere in a resistance of one ohm. One joule is approximately equal to 0.738 foot pounds
The Standard Electrical Dictionary
This term has been applied to several units. (a) The practical C. G. S. unit of electric energy and work--the volt-coulomb. It is equal to 1E7 ergs--0.73734 foot pound.--.00134 horse power seconds. A volt-ampere represents one joule per second. (b) It has also been used as the name of the gram-degree C. thermal unit--the small calorie. Synonym--Joulad.
