Coulomb ¹ Scientific  

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.

coulomb ² Scientific  

/ 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.

Etymology

Origin of coulomb

First recorded in 1880–85; after Coulomb

Example Sentences

This “coulomb explosion” destroys the involved molecule to get just one still image, so the researchers had to repeat the process 651 times and layer the pictures together like a quantum flip-book.

From Scientific American

The coulomb is the standard unit of an electric charge.

From Washington Post

The roentgen, describing air ionization, became a measurement in coulombs per kilogram.

From Nature

Because both qubits are positively charged, their motion is strongly coupled electrically through a phenomenon known as mutual coulomb repulsion.

From Scientific American

The capacity of a condenser which would contain a charge of one coulomb under one volt pressure is the farad.
