I'm confused by the definition of dielectric constant. We all know that dielectric is function of wavelength, because materials respond in different ways depending on the energy of the light. But w...

Feb 18, 2016 · Dielectric constant is the ratio of permittivity of a medium to the permittivity of free space. How to find dielectric constant of a conductor?

Jan 9, 2016 · I'm wondering what the dielectric constant or permittivity of metals is --particularly copper. Do metals have an infinite permittivity?

Jan 15, 2021 · The questions asks that, given the (surface) charge density (σ) on the plates of a parallel plate capacitor and dielectric constant (k), what would be the magnitude of induced charge density …

Mar 17, 2015 · A dielectric effectively behaves as if it was thicker than it is. If the dielectric constant is K K and the thickness of the dielectric is t t, then for calculating the force it behaves as if the thickness …

for two capacitors in series one usually assumes that the charge on C1 C 1 is the same as the charge on C2 C 2. Now if you have one capacitor partially filled with a dielectric one can think of this as two …

Jul 5, 2022 · The dielectric constant is one of them, as it is the degree of response of a material to an applied electric field. In summary, the dielectric constant (and other responses to external …

Apr 29, 2017 · Why is induced electric field due to bound charges in dielectric always less than the external electric field?

Jun 26, 2025 · $\varepsilon_2$ is the imaginary part of the dielectric constant $\varepsilon$ and describes absorption. So if $\varepsilon_2$ is negative, it would mean that the material is able to …

Jun 10, 2020 · The decrease in Potential energy of a parallel plate capacitor due to a dielectric is because the slab would start to oscillate and the energy would transfer back and forth between the …
