Polarization Density Formula

Equation for calculate polarization density is,

P = ϵ₀ · χ · E

where,
ϵ₀ = electric constant [ 8.854187817e-12 Fm^-1 ]
χ = Electric susceptibility of the medium ( indicates the degree of polarization of a dielectric material in response to an applied electric field)
E = Electric field (V/m)
P = Polarization density
