Answer:
Silver has least resistance
Explanation:
The given data :-
i) Since the diameter of each wire is same so the area of each wire is same i.e A₁ = A₂ = A₃.
ii) Length of each wire is same i.e L₁ = L₂ = L₃.
iii) Resistivity of copper ( ρ₁ ) = Ω.m
iv ) Resitivity of aluminum ( ρ₂ ) = Ω.m
v ) Resitivity of silver ( ρ₃ ) = Ω.m
Resistance is given by
Since the area and length are same of all three wire so it becomes constant.
R ∝ ρ
So by observing the resistivity of all three wire.
ρ₃ < ρ₁ < ρ₂
Therefore the wire silver has least resistance since it has least value of resistivity.
