Language:enStatus: Standard
Term: electric polarization
Synonym1:
Synonym2:
Synonym3:
Symbol: P
Definition: at a given point within a domain of quasi-infinitesimal volume V, vector quantity equal to the electric dipole moment p of the substance contained within the domain divided by the volume, V

P = p /V

Note 1 to entry: The electric polarization P satisfies the relation
