Learning about the nature of current, the Ampere and its role in Epsilon0. I'm assuming that the fact that the Ampere is defined in terms of electrons per second is arbitrary and that it could just as well have been protons per second? And if it had been protons per second, then Epsilon0 would still have the same value and sign because it makes use of Amperes squared, which will come out positive regardless of whether or not Amperes are defined in terms of negative or positive charge per unit time. Is this true?
