electric polarization
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 MathType@MTEF@5@5@+=feaagCart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLnhiov2DGi1BTfMBaeXatLxBI9gBaerbbjxAHXgarqqtubsr4rNCHbGeaGqipG0dh9qqWrVepG0dbbL8F4rqqrVepeea0xe9LqFf0xc9q8qqaqFn0lXdHiVcFbIOFHK8Feea0dXdar=Jb9hs0dXdHuk9fr=xfr=xfrpeWZqaaeqabiGaciGacaqadmaadaqaaqaaaOqaaGqadiaa=bfacqGH9aqpcaaMe8UaaGjbVpaalaaabaGaa8hCaaqaaiaadAfaaaaaaa@3C25@

Note – The electric polarization P satisfies the relation

D = ε0E + P

where D is the electric flux density, E the electric field strength and ε0 the electric constant.

D = ε0E + P

D est l’induction électrique, E le champ électrique et ε0 la constante électrique.
