coulomb Definition

cou·lomb (ko̵̅o̅′läm′, -lōm′)

noun

the basic unit of electric charge in the SI and MKS systems, equal to the charge of 6.281 × 10 electrons; the charge carried by a current of one ampere in one second: abbrev. C

Etymology: after C. A. de Coulomb (1736-1806), Fr physicist

coulomb Usage Examples

Preposition: of

  • charge: An electrical source supplies energy to each coulomb of charge which passes round a circuit.

Modifies a noun

  • term: See " molecule " if you wish to remove the coulomb terms.
  • matrix: Note that the DFT calculations did not exploit CD fitting, but evaluated the coulomb matrix explicitly.
  • excitation: Coulomb excitation, which interferes coherently with the strong interaction, is a program option.
  • explosion: We are primarily interested in the dynamics of multiple ionization in atoms, and dissociation and Coulomb explosion in molecules.
  • fit: Corresponding speedups when using the coulomb fit are 75 and 100 respectively.

Preposition: per

  • kilogram: The unit of exposure is the coulomb per kilogram of air.
  • centimeter: Other glass systems typically will produce a stable gain operating period of about one to ten coulombs per square centimeter.
  • volt: State that the unit of capacitance is the farad and that one farad is one coulomb per volt.
