/ 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.

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

One coulomb of electricity in passing through the cell liberates .000010352 of a gramme of hydrogen, and causes .00063344 of a gramme of zinc to dissolve in the acid.
