1. The resistance of a cylindrical brass conductor 0.5 cm diameter and 3m long are 0.0108 ohms. Determine resistance of a cylindrical conductor of the same material at the same temperature and having a diameter of 0.25 cm and a length of 8m.

2) A cylindrical copper rod having a diameter of 0.40in has a resistance of 0.00264 ohms. Taking the resistivity of copper as 1.745 μΩ-cm at 20° C, determine

a)the length of the rod in ft

b) 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.
