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:
“Flabby, bald, lobotomized,
he drifted in a sheepish calm,
where no agonizing reappraisal
jarred his concentration of the electric chair—
hanging like an oasis in his air
of lost connections. . . .”
—Robert Lowell (1917–1977)
“Never for a moment have I had one doubt about my religious beliefs. There are people who believe only so far as they can understand—that seems to me presumptuous and sets their understanding as the standard of the universe.”
—Woodrow Wilson (1856–1924)
