Definition:Electric Displacement Field

Definition
The electric displacement field is a vector quantity defined as the electric field strength multiplied by the permittivity of the medium through which it passes:
 * $\mathbf D = \varepsilon \mathbf E$

where:
 * $\varepsilon$ is the permittivity of the medium
 * $\mathbf E$ is the electric field strength

Also known as
An electric displacement field is also known as electric induction.
