A wire 6.50 m long with diameter of 2.05 mm has a resistance of 0.0290 $\Omega$. What material is the wire most likely made of?
Added by Kathleen C.
Step 1
Given diameter = 2.05 mm = 2.05 x 10^-3 m Radius = diameter/2 = 2.05 x 10^-3 / 2 = 1.025 x 10^-3 m Show more…

A wire 4.00 $\mathrm{m}$ long and 6.00 $\mathrm{mm}$ in diameter has a resistance of 15.0 $\mathrm{m} \Omega .$ A potential difference of 23.0 $\mathrm{V}$ is applied between the ends. (a) What is the current in the wire? (b) What is the magnitude of the current density? (c) Calculate the resistivity of the wire material. (d) Using Table $26-1,$ identify the material.
