if you look at the voltage current relationship at the input side of a
voltage regulator, you'll note that it acts like a negative resistor.
as the voltage source increases, the current decreases.
my question is, could you get a super conducting (zero resistance)
element by putting a resistor in series with the negative resistor?
You already have that situation at the voltage regulator output. The
voltage regulator's "negative resistance" is compensating for the
positive resistance of the source.
Note this isnt a useful superconductor-- it won't do
superconductor-like things, like hold a permanent current flow, expel
magnetic fields, dissipate zero power, etc....
