Electric Susceptibility Formula

Equation for calculate electric susceptibility is,

$\mathrm{\chi _e}=\frac{\mathrm{P}}{\mathrm{\epsilon ₀\; \times \; E}}$

where,
P is the polarization density
ε₀ is the electric permittivity of free space (8.854187817e-12 Fm^-1)
E is the electric field
χ_e is the electric susceptibility
