# Distribution of charges in an electrostatic study

I have a question concerning the capacitive coupling between two conductors. The capacitance C between the two is only a function of the diameter of the 2 studied conductors, the insulation thickness of the latter and distance between the two. My question is, since the charge on each conductor is equal to |Q| =|C*V| where V is the potential difference between the two conductors, the charge distribution should remain the same as long as V=1, right?

• The capacitance is the same no matter the voltage distribution, it characterizes the coupling between the two conductors. I asked the question because when running a FE simulation, the charge varies with the voltage (even though the difference of potential remains =1) – Wallflower Nov 19 '20 at 16:08
• Is there a ground anywhere other than infinity? – Neil_UK Nov 19 '20 at 16:23
• only infinity considered as the ground for this case study – Wallflower Nov 19 '20 at 16:30
• Don't conflate total charge with charge distribution. They are not the same thing. – Elliot Alderson Nov 19 '20 at 19:07
