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.

Resistivity : ρ = \(\frac{m}{ne^{2}t}\)

m : mass

n : number density

e : charge on electron

t : relaxation time
