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?
Answer & explanation
Correct answer: option 1
Resistivity : ρ = \(\frac{m}{ne^{2}t}\)
m : mass
n : number density
e : charge on electron
t : relaxation time
