They are said to be at different potentials, or to have a potential difference between them.

But that does not matter, because the question concerns about the potential difference.

It is independent of the potential difference between the conductors and the total charge on them.

This is the ratio of the electric charge on each conductor to the potential difference between them.

So at any two points on the same node, the change in potential difference is 0.

There's a big potential difference between the top of the atmosphere and the ground.

There is a great potential difference between that and your actual physical form.

A potential difference is the amount of energy to be able to pass from one energy to another.

The current and potential difference are everywhere 90 out of phase.

Look for a tough game, with home field the potential difference.
