In Searle's method for finding conductivity the temperature gradient along the bar is :

A

greater near the hot end

B

greater near the cold end

C

the same at all points

D

increases as we go from hot end to the cold end.

Text Solution

Verified by Experts

The correct Answer is:
C
In steady state temperature gradient is same at all points along the rod.
Hence correct choice is (c ).
