What is Thermal Resistance?

When two physical system are described by similar equations and have similar boundary conditions, these are said to be analogous. The heat transfer processes may be compared by analogy with the flow of electricity in an electrical resistance. As the flow of electric current in the electrical resistance is directly proportional to potential difference (dV); similarly heat flow rate , Q, is directly proportional to temperature difference (dt), the driving force for heat conduction through a medium.
