A wire allows electric current to pass through it freely because it has
Ainfinitely high resistance
Bvery high resistance
Cnegligible electrical resistance
Dzero mass
Answer & Solution
Correct answer: C. negligible electrical resistance
Materials that allow current to pass freely are conductors, and they are described here as having negligible electrical resistance.
High or infinite resistance would oppose current flow.
