Electric Susceptibility - Definition of Volume Susceptibility

Definition of Volume Susceptibility

Electric susceptibility is defined as the constant of proportionality (which may be a tensor) relating an electric field E to the induced dielectric polarization density P such that:

where

  • is the polarization density;
  • is the electric permittivity of free space;
  • is the electric susceptibility;
  • is the electric field.

The susceptibility is also related to the polarizability of individual particles in the medium by the Clausius-Mossotti relation. The susceptibility is related to its relative permittivity by:

So in the case of a vacuum:

At the same time, the electric displacement D is related to the polarization density P by:

Famous quotes containing the words definition of, definition and/or volume:

    It’s a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was “mine.”
    Jane Adams (20th century)

    Was man made stupid to see his own stupidity?
    Is God by definition indifferent, beyond us all?
    Is the eternal truth man’s fighting soul
    Wherein the Beast ravens in its own avidity?
    Richard Eberhart (b. 1904)

    Although volume upon volume is written to prove slavery a very good thing, we never hear of the man who wishes to take the good of it, by being a slave himself.
    Abraham Lincoln (1809–1865)
