Ответ:
A) False; B) False; C) True; D) False
Explanation: In order to explain this problem we have to take into account the expresion of the resistence of the condutor wire, which os given by:
R=ρ*L/A where ρ, L and A are the resistivity, length and area of the conductor.
As it can be seen, the resitence is inverse to the area so when the diameter decrease the resistance should increase its value. (A, C).
The resistivity does not depend on the length or diameter of the wire, only it depends on the material use to made the wire. (B,C and D).
