"The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical … See more Relative permittivity is typically denoted as εr(ω) (sometimes κ, lowercase kappa) and is defined as $${\displaystyle \varepsilon _{r}(\omega )={\frac {\varepsilon (\omega )}{\varepsilon _{0}}},}$$ See more The relative static permittivity, εr, can be measured for static electric fields as follows: first the capacitance of a test capacitor, C0, is measured with vacuum between its plates. Then, using the same capacitor and distance between its plates, the capacitance C … See more Again, similar as for absolute permittivity, relative permittivity for lossy materials can be formulated as: $${\displaystyle \varepsilon _{r}=\varepsilon _{r}'-{\frac {i\sigma }{\omega \varepsilon _{0}}},}$$ in terms of a … See more Energy The relative permittivity is an essential piece of information when designing capacitors, and in other circumstances where a material might be expected to introduce capacitance into a circuit.
