Hello , there are two questions I would like to ask from a educational paper i just read.
For the first question please look the attached picture , it says that in the picture of the capacitor with the wire that has a gap in the middle and next to it when the gap is closed , it says that in the exact middle of that wire between the two plates the wire is neutral , that would imply no charge , well first of all even if that happens , for how long as i basically see a charged capacitor being short circuited with a wire which would basically discharge the cap.
Let me rephrase the question , imagine a LC parallel tank circuit , only in the middle of the inductor cut the wire in half and place a switch in series , now charge the capacitor while the switch is open , once the capacitor is charged , close the switch , the question is for the first instant would the switch being in the middle feel any current/voltage through it ? as the current would form when the switch is closed but because going through an inductor it would build up a magnetic field which would oppose the current so at the first instant the inductor would act as a " choke" , so what happens with the switch in the middle ?
there has been some discussion about this here on PF but I still haven't got a clear answer so I'm going to ask this one more time.
The paper i read says that the electric potential is independent of the value of q ,(q being the fundamental charge strength of a charged particle)
So does that mean that I can have one electron at say million volts of potential which has the same field strength around it as say 10 electrons at the same potential or no?
