The coulomb, abbreviated C, is the SI unit of electric charge. It is defined as the amount of charge passing a point in one second in a circuit with one ampere of current.
The coulomb is named for French physicist Charles-Augustin de Coulomb (1736–1806). Coulomb also developed the law of electrostatic attraction and repulsion, which is named Coulomb's law in his honor.
The coulomb is a derived unit in the SI, equal to 1 A·s.
- C = A ⋅ s
One coulomb is −6.241 509 647 ·1018 times the charge e of an electron.[1]
