Question

resistance of a metallic conductor

Answer 1

Superconductivity. The electrical resistivity of a metallic conductordecreases gradually as temperature is lowered. In ordinary conductors, such as copper or silver, this decrease is limited by impurities and other defects. Even near absolute zero, a real sample of a normal conductor shows some resistance.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

THOSE CONDUCTOR WHICH ALLOW THE ELECTRIC CURRENT TO PASS THROUGH THEM WITHOUT ANY CHEMICAL CHANGE OR CALLED METALLIC CONDUCTORS.
