Main Question or Discussion Point
Is there such a thing in electrical circuits, or anywhere else? Or is this just considered reverse polarity, or 0V?
this negative potential that u are talking about is something that u've compared to infinity as if infinity has 0 potential, it is perfectly legal to say that negative charged particle create 0 potential at some point in space if u assign some positive potential value to thet 'infinity' placeI thought that might be the case with ions.. negative charged atoms (electrons) create negative potential.
As mentioned above the zero value of the electric potential is typically set to zero in those cases in which the electri potential falls to zero at infinity. However there are instances one runs into when working problems in electrostatics. For example; if you were studying electrostatics then a well-known problem is to find the electric potential of an infinitely long line of charge which has a uniform linear charge distribution. In this case the electric potential does not go to zero at infinity. The zero potential is then chosen to be at an arbitrary distance from the line of charge. Closer to the line the electric potential is zero, further from this distance the electric potential is positive.Is there such a thing in electrical circuits, or anywhere else?
