Three rods of identical cross-section and lengths are made of three different materials of thermal conductivity 
, and 
, respectively. They are joined together at their ends to make a long rod (see figure). One end of the long rod is maintained at 
and the other at 
(see figure). If the joints of the rod are at 
and 
in steady state and there is no loss of energy from the surface of the rod, the correct relationship between 
and 
is:
Text Solution
Verified by ExpertsA
Rods are identical have same length 
and area of cross-section
Combination are in series, so heat current is same for all Rods
Heat current
