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.

Does the 'internal potential energy' (created by charge separation) of a dipole have any phy...
If you have a dipole with charges $Q_+$ and $Q_-$ separated by a distance $d$ you could calculate the work done of separating these two charges the distance $d$
$$ \Delta U = q \Delta V = - \vec{F} \ …

Is the commonly derived Gauss' law for a parallel plate (insulator/conductor) often derived ... [duplicate]
I am very confused about plates (conductors/insulators) and applying Gauss law. It seems like gauss law for the isolator is very often derived wrongly.
In short: if you have an infinite plate (insulat …

Which charges pushes exactly a charge inside a conductor to the surface and why does it pref...
I know this has a lot of questions about it, however my question is different: why does a charged particle inside a conductor get pushed toward the surface?
The usual explanation is that in a conducto …

Definition of the electric field
The test charge must be very small because, according to Coulomb's Law, charges exert forces on each other. If the test charge $ Q_2 $ is large, it will influence the configuration of the source charg …
