Electrostatics is concerned with the electrical fields and scalar potentials of stationary electrical charges and charge distributions. Use this for questions about electromagnetic situations in which currents and magnetic fields are absent, otherwise use the [electromagnetism] and/or [magnetic-fields] tags.

Meaning of a sentence concerning the electric field inside its source charge
I think it just means you can't calculate the field 'inside' the point charge by using the 1/r^2 relation. By 'elementary sources' it is just talking about electrons, protons etc.

I want to calculate the electric field of a charged solid sphere without using Gauss's law
I can find the electric field from a charged solid sphere using Gauss's law but I am struggling to calculate this from Coulomb's law (I have seen examples of calculating e-field using Coulomb's law fo …

I want to calculate the electric field of a charged solid sphere without using Gauss's law
Following on from Arturo's answer (thanks) I think I have figured out how to solve the integration over the sphere to find the electric field at a point using spherical coordinates and vectors.

Electric displacement field $D$ - what do the terms in the definition represent intuitively?
In the following equation I would like to check what the terms represent intuitively (in a hand-wavey sense - I know $\underline{D}$ is not a physical thing so it's not possible to fully describe it i …

For a conductor in an external field, I would like to know whether the electron clouds of each atom, just shift slightly (resulting in positive charges just on one edge, and negative charges just on t …

When electrons go to the outside surface of a conductor why doesn't that create an electric ...
If an isolated conductor has a net zero charge and is not in an external field, would the free charges still move to the surface of the conductor eg. a conducting sphere? Wouldn't this create an elect …
