Chapter 5: Problem 13
A hollow cylindrical tube with a rectangular cross section has external dimensions of \(0.5 \mathrm{in}\). by 1 in. and a wall thickness of \(0.05 \mathrm{in}\). Assume that the material is brass, for which \(\sigma=1.5 \times 10^{7} \mathrm{~S} / \mathrm{m}\). A current of \(200 \mathrm{~A} \mathrm{dc}\) is flowing down the tube. \((a)\) What voltage drop is present across a \(1 \mathrm{~m}\) length of the tube? (b) Find the voltage drop if the interior of the tube is filled with conducting material for which \(\sigma=1.5 \times 10^{5} \mathrm{~S} / \mathrm{m}\).
