How do I compute the voltage accross a cell membrane given microstate of neuron (distribution of charged ions)?
I am not a physicist, and I'm not sure what keywords to use to search for this.
I'm trying to understand how I could in theory quantitatively know, what the voltage across a cell membrane in a Neuron ...

Chloride equilibrium potential is negative shouldn't it be positive?
Chloride flows down its concentration gradient into the cell. At a certain point a minute amount of net positive charge develops on the outside, enough to electrostatically attract chloride ions back ...

Why standard voltage is $110/220~\mathrm{V}$ and not $500~\mathrm{V}$?
Why do we have standard voltage $110/220~\mathrm{V}$?
I mean electricity delivery savings (or wastage when heating the to thin cable) by switching to higher voltage would be enormous more power ...

Voltage homogeneity across cell membrane
During respiration, individual cells produce a relatively large potential difference ($\sim 100$ mV) between the inside and outside, using energy to pump $H^+$ out of the cell to the liquid ...
