### Calculating Potential Difference between Electrodes

Why is it that when we calculate the potential difference between electrodes, we take the limit as it approaches zero?

I think it has to do with where he mentioned that without a potential difference, the battery ceases to function, so there needs to be some potential difference for the battery to continue to work and as it approaches zero, the battery does not transfer electrons or ions and the battery needs to be recharged, or given a potential difference

Yeah, I don't think it makes sense logically if we try to calculate the potential when it equals zero because wouldn't that mean that there was no difference? Haha, I don't know if I'm expressing myself clearly.

No that makes sense, because you can't actually calculate anything when it's at zero.
