## cou·lomb

(ko͞o′lŏm′, -lōm′)
n. Abbr. C
The basic unit of electric charge, equal to the quantity of charge transferred in one second by a steady current of one ampere, and equivalent to 6.2415 × 1018 elementary charges, where one elementary charge is the charge of a proton or the negative of the charge of an electron. A coulomb's value in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units. See Table at measurement.
Of or relating to the Coulomb force.

[After Charles Augustin de Coulomb.]

## cou·lomb

(ko͞o′lŏm′, ko͞o′lōm′)
A unit used to measure electric charge. One coulomb is equal to the quantity of charge that passes a point in an electric circuit in one second when a current of one ampere is flowing through the circuit.
