Answer:
infinity
Explanation:
Given that
Resistance = R
Resistivity = ρ
Length = L
Diameter = d
The resistance of wire R given as
[tex]R=\rho\dfrac{L}{A}[/tex]
A=Area
[tex]A=\dfrac{\pi d^2}{4}[/tex]
Now by putting the value of A
[tex]R=\rho\dfrac{L}{\dfrac{\pi d^2}{4}}[/tex]
[tex]R=\rho\dfrac{4L}{\pi d^2}[/tex]
When d tends to infinity then d² will also tends to infinity.
So when d tends to zero then the resistance tends to infinity.
Therefore answer is ---
infinity
