A slab consists of two parallel layers of two different materials of the same thickness having thermal conductivities $k_{1}$ and $k_{2}$ . The equivalent conductivity of the combination is:

Options:

Answer:

Solution:

Layers side by side of equal area are in parallel. $k_{e q} (2 A) = k_{1} A + k_{2} A$ , so $k_{e q} = \frac{k _{1} + k _{2}}{2}$ . B.
