/ ko̅o̅′lŏm′,ko̅o̅′lōm′ /

1. 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

²

1. 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.
