(a) Compute the electrical conductivity of a 5.1mm diameter cylindrical silicon specimen 51 mm 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. (b) Compute the resistance over the entire 51 mm of the specimen.
