Cars & Driving

  • noun a definite quantity of electricity, which may be positive, as with protons, or negative, as with electrons.


  • noun the presence of a number of atoms that are charged, because of an excess or deficiency of electrons


  • A basic property of subatomic particles, atoms, molecules, and the antimatter counterparts of each of these. An electric charge may be negative, positive, or there may be no charge. The net charge of a body is the sum of the charges of all its constituents. For instance, a cation has a net deficiency of electrons, so its charge is positive. Each electric charge, whether positive or negative, is equal to 1.6022 × 10-19 coulomb, the charge of an electron, or a whole number multiple of it. Also called charge (1).
  • The electrical energy stored in, or on the surface of an insulated body such as a storage battery or capacitor. Usually expressed in coulombs. Also called charge (2).
