electric moment

[i¦lek·trik ′mō·mənt]

(electricity)

One of a series of quantities characterizing an electric charge distribution; an l-th moment is given by integrating the product of the charge density, the l-th power of the distance from the origin, and a spherical harmonic Y *_lmover the charge distribution.
