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.
