SUMMARY
Electric susceptibility (χ) is defined as the relative permittivity (κ) of a dielectric minus one, expressed mathematically as χ = κ - 1. This relationship indicates that while χ may seem redundant, it serves a practical purpose in simplifying equations. The polarization (P) of a dielectric is given by the equation P = χE, while the electric displacement (D) is described by D = κε₀E. Both χ and κ are essential in different contexts within electromagnetism.
