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...

Mar 7, 2021 · In few questions, I am having some confusion on how to take the resultant capacitance of a parallel plate capacitor with a combination of dielectric in between parallel plates.

Jun 9, 2020 · 2 According to the definition of the dielectric constant (k) for a dielectric, the electric field in the dielectric is defined as the corresponding electric field in vacuum divided by k. We are also aware …

Mar 5, 2023 · Trick question: Dielectric material produces net surface charge when placed in electric field. Isolated conductor also produces net surface charge when placed in electric field. However, …

Feb 29, 2024 · So, most dielectric materials are modeled with a variable dielectric constant (or tensor) that accounts for polarization of the underlying medium (induced dipoles, etc.) Because energy is …

Dec 3, 2022 · 2 We have a conductor of resistivity ρ ρ and has a boundary with a dielectric of permittivity ϵ ϵ and we have displacement vector D→ D → at an angle α α with normal to the boundary and …

Jan 27, 2025 · Further, this would imply that the equation for net displacement current in a dielectric medium would be $\epsilon_ok \frac {d\phi_E} {dt}$ However, this result doesn't make intuitive sense …

Dec 19, 2016 · According to Dielectric to Dielectric Boundary conditions, the tangential components of the electric field E remain continuous at the boundary of two dielectrics while the tangential …

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

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?
