### Problem 4.37 from Griffiths electrodynamics [closed]

The problem says : "A point dipole p is imbedded at the center of a sphere of linear dielectric material (with radius $R$ and dielectric constant k). Find the electric potential inside and ...

### What's the general rules of the relationship of permittivity of different materials?

As we know the real part of permittivity is dielectric constant $\varepsilon^{'}$, and the imaginary part of permittivity is dielectric loss $\varepsilon^{''}$. So are there general rules of the ...

### Laplace's equation in presence of a dipole

I know that in classical electrodynamics we're dealing with stuff macroscopically, so I can pretend that some volume of space is empty of charge when it's actually full of matter consisting of charged ...

### Is there a similar process like hysteresis for dielectrics/dipoles?

Hysteresis is shown in the following image from hyperphysics: Does a similar curve exists for dipoles? For example given a dielectric medium inside a capacitor, the electric field will induce a ...

### How to derive the Electric field from the magnetic field?

Given a linearly polarized, monochromatic plane wave with $H = H_0y^{cos(kz − ωt)}$ traveling in the $+\hat{z}$ direction that is incident on a dielectric sphere with permittivity $e$ and radius $a$, ...

### Work and Dielectric Shell

Consider a dielectric shell with inner radius R1 and outer radius R2, if I were to carry a point charge q from infinity to the center of the shell, what is the total work done by me? This is the ...

### Static dielectric constant and optical dielectric constant

I was reading Introduction to Solid State Physics of Charles Kittel (8th Edition), and the static dielectric constant is defined as $$\epsilon(0) = \epsilon(\omega=0)$$ and the optical dielectric ...

### Capacitors filled with parallel $n$ dielectrics
I'll be brief. In cases where we have a capacitor filled with an $n$-amount of different dielectrics, each and everyone one right next to the other, is it okay to re-think the problem as having n ...
