  1. 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

  2. Joule, James Prescott Joule(noun)

    English physicist who established the mechanical theory of heat and discovered the first law of thermodynamics (1818-1889)

GCIDE

  1. joule(n.)

    A unit of work which is equal to 107 ergs (the unit of work in the C. G. S. system of units), and is equivalent to one watt-second, the energy expended in one second by an electric current of one ampere in a resistance of one ohm; also called the absolute joule. It is abbreviated J or j. The international joule is slightly larger, being 1.000167 times the absolute joule. The absolute joule is approximately equal to 0.737562 foot pounds, 0.239006 gram-calories (small calories), and 3.72506 x 10-7 horsepower-hours, and 0.000948451 B.t.u. HCP61

  2. Origin: [From the distinguished English physicist, James Prescott Joule (1818-1889).]

Wiktionary

  1. joule(Noun)

    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

  2. Origin: Named after the English physicist James Prescott Joule.

Webster Dictionary

  1. Joule(noun)

    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

  2. Origin: [From the distinguished English physicist, James Prescott Joule (1818-1889).]

Freebase

  1. Joule

    The joule, symbol J, is a derived unit of energy, work, or amount of heat in the International System of Units. It is equal to the energy expended in applying a force of one newton through a distance of one meter, or in passing an electric current of one ampere through a resistance of one ohm for one second. It is named after the English physicist James Prescott Joule. In terms firstly of base SI units and then in terms of other SI units: where N is the newton, m is the meter, kg is the kilogram, s is the second, Pa is the pascal, and W is the watt. One joule can also be defined as: ⁕The work required to move an electric charge of one coulomb through an electrical potential difference of one volt, or one '"coulomb volt". This relationship can be used to define the volt. ⁕The work required to produce one watt of power for one second, or one "watt second". This relationship can be used to define the watt.

The Standard Electrical Dictionary

  1. Joule

    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.

Sample Sentences & Example Usage

  1. Deodatta V. Shenai-Khatkhate:

    I still remember two life-sized marble statues of two great scientists in the corridor of Manchester Town Hall, which I saw many years ago. One of them is of John Dalton, the founder of modern Chemistry and the Atomic Theory, while the second statue is of James Prescott Joule, the founder of modern Physics and the discoverer of the Law of Conservation of Energy. I consider myself very fortunate to be the student of the University of Manchester, the home of great scientists, Dalton and Joule. And most importantly, I am proud to be the recipient of Dalton Chemical Research Scholarship that enabled me to obtain my Ph.D. I am thankful to The University of Manchester as much as to John Dalton's Trust Foundation, for the greatest educational experience of my life.

  2. Deodatta V. Shenai-Khatkhate:

    Je me souviens encore deux statues de marbre grandeur nature de deux grands scientifiques dans le couloir de la mairie de la ville de Manchester, qui je l'ai vu il ya plusieurs années. l'un d'eux est de John Dalton, le fondateur de la chimie moderne et la théorie atomique, tandis que la seconde statue est de James Prescott Joule, le fondateur de la physique moderne et le découvreur de la loi de conservation de l'énergie. Je me considère très chanceux d'être l'étudiant de l'Université de Manchester, la maison de grands scientifiques, Dalton et Joule. Et surtout, je suis fier d'être le récipiendaire de la bourse de recherche daltons chimique qui m'a permis d'obtenir mon doctorat Je suis reconnaissant à l'Université de Manchester autant que la fondation de la confiance à John Dalton, pour la plus grande expérience de l'éducation de ma vie.
