Answer:
L=5882.35 m
Explanation:
Given that
Area ,A= 1 cm²
Resistivity ,ρ = 1.7 x 10⁻⁸ Ω ∙ m
Resistance ,R= 1 Ω
Lets take length of the wire = L
[tex]R=\rho \times \dfrac{L}{A}[/tex]
Resistivity =ρ
Resistance =R
Area =A
Resistance =R
[tex]L=\dfrac{R\times A}{\rho }[/tex]
Now by putting the values in the above equation get
[tex]L=\dfrac{1\times 1\times 10^{-4}}{1.7\times 10^{-8} }\ m[/tex]
L=5882.35 m
Therefore the length of the wire will be 5882.35 m.
