Definition

vector quantity given by

D = ε_{0} E + P

where $ε_{0}$ is electric constant (electric constant), $E$ is electric field strength (electric field strength), and $P$ is electric polarization (electric polarization)

grandeur vectorielle donnée par

D = ε_{0} E + P

où $ε_{0}$ est la constante électrique (electric constant), $E$ est le champ électrique (electric field strength) et $P$ est la polarisation électrique (electric polarization)

Notes

The electric flux density is related to electric charge density via $div D = ρ$ where $div$ denotes divergence.

The electric flux density, the electric field strength, and the polarization depend on the position.

See IEC 60050-121,locality:item="121-11-40".

L'induction électrique est liée à la charge électrique volumique par $div D = ρ$ où $div$ désigne la divergence.

L'induction électrique, le champ électrique et la polarisation dépendent de la position.
