Reading some books there is something that i don't understand. Is the capacitors topics when they name a potential difference between conductors. As i know, Potential difference is the difference in electric potential energy per unit charge between two points.

So, talking about capacitors, the potential difference between conductors is:

a) The difference between the potential of each conductor.
b) The difference of potential between those 2 points: (conductor)·     ·(conductor)

Electrical conductors are equipotential surfaces. So both of your choices give the same answer.

  • $\begingroup$ Analogy to what? $\endgroup$ – Vijay Murthy May 1 '12 at 20:35
  • $\begingroup$ Sorry, its so hard to explain, i mean, which one would be your first thought about potential difference between conductors. $\endgroup$ – nEAnnam May 1 '12 at 20:40
  • $\begingroup$ I am lost. Both your choices are correct for the case of conductors. So what is the confusion here? $\endgroup$ – Vijay Murthy May 2 '12 at 8:56
