i) Determine electrial conductivity of the 5.1 mm (0.2 in) diameter cylindrical silicon specimen 51 mm (2in) long in which current of 0.1 A passes in the axial direction. The voltage of 12.5 V is estimated across two probes which are separated by 38 mm (1.5 in).
ii) Calculate resistance over entire 51 mm (2in) of specimen.
