Consider two rods of equal cross - sectionai area A, one of Aluminium and other of iron joined end to end as shown in figure -4.8. Length of the two rods and their thermal coductivities are `l_(1) , k_(1)`and `l_(2),k_(2)` respectively . If the ends of the rods are maintained at temperature `T_(1)` and `T_(2),(T_(1)gt T_(2))` find the temperature of the junction in steady state .
