Consider two conductors A and B such that the number density of electrons in conductor A is half of that in conductor B. What will be the resistivity of conductor A w.r.t. conductor B? |
The resistivity of conductor A will be double that of conductor B. The resistivity of conductor A will be half that of conductor B. The resistivity of conductor A will be four times that of conductor B. The resistivity of conductor A will be 1/4 of that of conductor B. |
The resistivity of conductor A will be double that of conductor B. |
