Coulomb (from Augustus de Coulomb, 1736-1806, an officer of engineers in the French army and a distinguished physicist), in Electricity, is the name given to the unit quantity of electricity. A current of one ampere, i.e. a unit current, flowing past any section of a conductor for a second, involves the displacement of one coulomb of electricity past the section in that time. A coulomb of electricity sent through a silver voltameter will deposit .000010352 gramme of silver, however long it take to pass through; a small current flowing for a long period having the same effect as a large current flowing for a short interval.
