(a) Compute the electrical conductivity of a 5.1-mm (0.2-in.) di

(a) Compute the electrical conductivity of a 5.1-mm (0.2-in.) diameter cylindrical silicon specimen 51 mm (2 in.) long in which a current of 0.1 A passes in an axial direction. A voltage of 12.5 V is measured across two probes that are separated by 38 mm (1.5 in.).
(b) Compute the resistance over the entire 51 mm (2 in.) of the specimen.
