A partition wall has two layers
and
in contact, each made of a different material. They have the same thickness but the thermal conductivity of layer
is twice that of layer
. If the steady state temperature difference across the wall is
, then the corresponding difference across the layer
is
Text Solution
Verified by ExpertsThe correct answer is:
B
Suppose conductivity of layer B is K, then it is 2K for layer A. Also conductivity of
