coulomb

Ampere times second

A coulomb is the standard unit of electric charge, equal to the quantity of electricity transferred by a current of one ampere in one second.

It appears in physics and electrical engineering contexts: The capacitor stores several coulombs of charge.

Named after the French physicist Charles-Augustin de Coulomb, though the unit itself takes lowercase. (Capitalized Coulomb refers to the physicist or his law.)
