Where can this uniqueness theorem of electrostatic be found?
There is a nice uniqueness theorem of electrostatics, which I have found only after googling hours, and deep inside some academic site, in the lecture notes of Dr Vadim Kaplunovsky:
Suppose some volu …

Floating potential of a conductor near another conductor with known potential with respect t...
Electrostatics textbooks delight at computing the electric field or the potential created by a known distribution of charge, ignoring the fact that this is rather a non practical question. In practica …

Experiment interpretation. Dielectric polarization/triboelectricity/other?
My aim was to create a relatively strong electrostatic field to experiment with biological systems. So, I built a kind of "sandwich" made of a plate of aluminium surrounded by two 4mm plates of isolat …

Electric potential vs electromagnetic potential questions
Building on the answer of Ján Lalinský and on further research, I add here my own answer to the question.
question 1: It turns out that the electric potential $V$ measured at some point of the wires i …

Electric potential vs electromagnetic potential questions
We were all taught about the electric potential $V$, which is defined up to a constant, and can be measured with a voltmeter or an oscilloscope.
On the other hand, in electromagnetism are defined the …
