A semiconductor material with k = 2 W/m K and electrical resistivity, = 2

A semiconductor material with k = 2 W/m · K and electrical resistivity, ρ = 2 × 10^-5 Ω - m, is used to fabricate a cylindrical rod 40-mm long with a diameter of 10 mm. The longitudinal surface of the rod is well insulated and may be considered adiabatic while the ends are maintained at temperatures of 100°C and 0°C, respectively. If the rod carries a current of 10 amps, what will be its midpoint temperature? What will be the rate of heat transfer through both ends?
