    The web page says:

    "Defined in the context of static electricity, voltage is
    the measure of work required to move a unit charge
    from one location to another, against the force which
    tries to keep electric charges balanced."

    The amount of work required to move a unit charge
    through an electric field isn't voltage, it's energy
    (measured in joules). Yes, even if you move one coulomb
    of charge, it doesn't magically convert work to voltage.
    One could say (in this case) work done in joules is
    numerically equal to the voltage of the field in volts.
    However, it's usually clearer to define voltage
    (physical dimension) first, and then volts (unit of measure)
    second.

    DAvid Lewis,

    While what you say is true, I don't think I really need to change the text.
