    Doubling the voltage from 2500 to 5000 does not double the velocity of the electrons. Why not?

    One question. The voltage of what?
    Is this about the drift velocity of electrons in a wire, the acceleration of electrons in an electric field between two plates, or somewhere else? The answer depends a lot on the situation.

    Assuming you're talking about drift velocity in a wire, think about the relationship between the kinetic energy of an electron and it's velocity, if you double one does the other just double?
