Two ends of a conducting rod of varying cross sections are maintained at 200 C and 0 C respectively In steady state B CD 0 C 200 C 1 temperature difference across AB and CD are equal 2 temperature difference across AB is greater than that of across CD 3 temperature difference across AB is less than that of across CD 4 temperature difference may be equal or different depending on the thermal conductivity of the rod
