Metals typically have resistivities in which range?
A10^-2 to 10^0 ohm m
B10^2 to 10^4 ohm m
C10^-8 to 10^-6 ohm m
D10^10 to 10^12 ohm m
Answer & Solution
Correct answer: C. 10^-8 to 10^-6 ohm m
Good metallic conductors have resistivities of roughly 10^-8 to 10^-6 ohm m, far lower than semiconductors or insulators.
