## coulomb

Noun

(*plural* coulombs)

- In the International System of Units, the derived unit of electric charge; the amount of electric charge carried by a current of 1 ampere flowing for 1 second. Symbol: C

- Jewelry: pendant. From the homophone for Coulomb in Russian, кулон.

## coulomb - Computer Definition

A standard unit of electrical charge. Pronounced "kool-**ahm**," one coulomb (C) is equivalent to one amp of current flowing through a conductor for one second. It is also equal to 6.25 quintillion electrons (6.25 X 10 to the 18th). From French physicist Charles de Coulomb (1736-1806), who measured the behavior of electrical charges. See capacitance.

The unit of electric charge equal to the quantity of electricity transferred by one ampere (A) in one second, a coulomb is the flow of 6.24
