Question

A cylindrical copper rod having a diameter of 0.40 in has a resistance of 0.00264 Ω. Taking the resistivity of copper as 1.745 µΩ-cm at 20^o C, determine
- the length of the rod in ft.
- resistance of the rod when it is drawn down to one-third of the initial diameter, the volume remaining unchanged. Assumed that the resistivity of the copper is not affected by the drawing process.
