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.

Potential at a point on the plate of a parallel plate capacitor
In the two plates of a parallel plate capacitor, the charges are equal and opposite i.e $q$ and $-q$. Can I say the potentials of these plates as $V_1$ and $-V_1$, so the difference in potentials will …

How to use Gauss's law on the surface of a conductor?
I have seen that the electric field on the surface of a conductor of any shape is $$E=\frac{\sigma}{\varepsilon_0}\; .$$
I have already got that the field near the surface of a conductor but my concer …

What exactly is meant by potential of a plate?
while going through capacitors, what exactly does the term potential of a plate mean?
does potential of a plate mean potential "at any point" on the plate, i.e the work done in bringing a unit positiv …
