got a question about the definition of an electron volt. The net says that it is the kinetic energy gain when an electron moves thru a potential diference of 1 volt. But the distance between the positive and negative source of that 1 volt... does it not matter or affect the definition? Because this distance is never mentioned in the definition.

An electron that is stationary but then suddently exposed to a + and - charge source 1 meter apart and the - source positions it self right on the electron so the electron flies to the + source and at that instant when it reaches the + charge source has a total kinetic energy x which we all think is 1 electron volt right? Would the result be diferent if instead of 1 meters the distance between the + and - charge sources was 2 meters or 100 meters?

Nothing is mentioned also about how long the electron has to be exposed to the 1 volt to gain 1 electron volt.
