Coulomb was the maker of the first instrument for measuring a current, which was known as the torsion balance.
In determining the exact quantity of an electric current, physicists make use of a device called a coulomb meter.
The coulomb is defined as the quantity of electricity delivered by a current of one ampere during one second.
