In physics, the electric dipole moment is a measure of the separation of positive and negative electrical charges in a system of charges, that is, a measure of the charge system's overall polarity. The SI units are Coulomb-meter (C m). This article is limited to static phenomena, and does not describe time-dependent or dynamic polarization.

Famous quotes containing the words electric and/or moment:
“That’s the down-town frieze,
Principally the church steeple,
A black line beside a white line;
And the stack of the electric plant,
A black line drawn on flat air.”
—Wallace Stevens (1879–1955)
“Consider any individual at any period of his life, and you will always find him preoccupied with fresh plans to increase his comfort. Do not talk to him about the interests and rights of the human race; that little private business of his for the moment absorbs all his thoughts, and he hopes that public disturbances can be put off to some other time.”
—Alexis de Tocqueville (1805–1859)
