This quantity increases drastically when the breakdown voltage is exceeded.
The time-dependence of the real and imaginary parts of this quantity can be depicted using a ColeÂ–Cole plot, which describes how this quantity undergoes Debye relaxation to its normal value when an applied field is removed. Materials are classified as having "high" or "low" values of this quantity depending on how their properties compare to silicon dioxide. A material's absolute value for this quantity divided by the standard value for this quantity equals one plus the electric (*) susceptibility. This quantity increases drastically when the breakdown voltage is exceeded. This quantity is also called relative permittivity. For 10 points, name this quantity, symbolized lowercase kappa, that multiplies the capacitance of a parallel-plate capacitor when an insulator is placed between the terminals.
