Two rods of copper and brass ( 
) of same length and area of cross-section are joined as shown in figure. End A is kept at 
and end B at 
. The temperature at the junction
A
will be more than 
B
will be less than 
C
will be 
D
cannot say
Text Solution
Verified by ExpertsThe correct answer is:
A
Given, 
Temperature difference across copper
…(i)
and temperature difference across brass
…(ii)
Heat current 
will be same in both, as they are in series ．
Since ， 
［ From Eqs. (i) and (ii)]
or temperature of junction is more than 
．
