Dielectric constantRelated: The relation D = εE uses permittivity to connect field and displacement.
PermittivityRelated: Permittivity relates this field to the electric field in a material.
Vacuum permittivityRelated: In vacuum, electric displacement equals ε₀ times the electric field.
Electric fluxRelated: Its flux through a closed surface counts enclosed free charge.
Relative permittivityRelated: Its relation to the electric field includes permittivity.
