The thermal resistance $RH$ of a metallic conductor of length $L$, cross-sectional area $A$, and thermal conductivity $K

Question

The thermal resistance $RH$ of a metallic conductor of length $L$, cross-sectional area $A$, and thermal conductivity $K$ is given by:

Accepted Answer

By analogy with electrical resistance ($R = \rho L/A = L/(\sigma A)$), thermal resistance is defined as $RH = \frac{L}{K A}$. Hence, option A is correct.
