Understanding the Units

What is a Coulomb?

The coulomb is the SI derived unit of electric charge, equal to the charge transported by one ampere in one second (1 C = 1 A·s).

Named after Charles-Augustin de Coulomb (1736–1806), French physicist who quantified the electric force law.

Common contexts: electrostatics, chemistry.
