I understand what you are saying, but the OP specified both 0 resistance and 0 inductance (so 0 impedance, real and imaginary). Obviously it is unphysical, but in principle you cannot apply any voltage across it.

I'm sorry, but i cannot seem to interpret your statement. In my opinion, a voltage can be applied across the abnormal conductor, just that it would not 'appear' across it as there is no impedance available for the voltage to drop across and 'reflect' itself externally...as all the voltage will be 'used up' in driving infinite current thru the said conductor! :rolleyes:

Since we're addressing an unphysical never-ever land, I think it could
Good point. If the premise gets rid of part of Maxwell's laws, why not some other part also.

Phrak is right, forget what I said. You are making up a magical conductor so feel free to make up a magical voltage as well. Use whatever fantasy-land answer you want.
