Time Traveler, re:<your assertion that a+b=a>

Your original statement was
Junction resistance + trace resistance = junction resistance.
found in post 5844.

I was merely pointing out that this is true only if b (a.k.a. trace resistance) = 0. This is certainly true at 0 degK, but not for any practical device. Furthermore you seem unfamiliar with engineering jargon, to wit:

Although the DC resistance goes to zero at the super-conducting temperature and material, does the AC resistance also go to zero as well?

The proper term for "AC resistance" is impedance.

I mention Ohm's law only because you should travel back in time to 1827, when it was discovered rather than wasting your time here.
