    Roughly:
       The conductor is a plasma
        The hotter, the better it conducts
       AND
       The hotter, the more 'conducting bits' (ions) there are.

     As current goes up, it gets hotter.

    SO, both these effects DROP the voltage across the
    'arc'.

    Roughly true for sparks as well.
