Main Entry: cou·lomb
Pronunciation: 'kü-"läm, -"lOm, kü-'
Function: noun
: the practical mks unit of electric charge equal to thequantity of electricity transferred by a current of one ampere in one second
Couálomb /ku-lOn/, Charles–Augustin de (1736–1806), Frenchphysicist. A pioneer in electrical theory, Coulomb is known for his formulation of the law (now identified with him) in physics regarding the force between two electrical charges. He also establishedthat the attraction and repulsion of unlike and like magnetic poles varies inversely as the square of the distance between them. In the course of his career Coulomb did research on friction as appliedto machinery, on windmills, and on the elasticity of metal and silk fibers. The electrical unit of measure was named in his honor in 1881 by the Paris Congress on electricity.

Science Dictionary
coulomb   (k'lŏm', k'lōm')  Pronunciation Key 
The SI derived unit used to measure electric charge. One coulomb is equal to the quantity of charge that passes through a cross-section of a conductor in one second, given a current of one ampere.
Coulomb, Charles Augustin de 1736-1806.  
French physicist who was a pioneer in the study of magnetism and electricity. He is best known for the formulation of Coulomb's law, which he developed as a result of his investigations of Joseph Priestley's work on electrical repulsion. Coulomb also established a law governing the attraction and repulsion of magnetic poles. The coulomb unit of electric charge is named for him.

coulomb

unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere. Named for the 18th-19th-century French physicist Charles-Augustin de Coulomb, it is approximately equivalent to 6.24 1018 electrons. See electric charge.
