Electrical Analogy Of Heat Conduction

Tank is made of acrylic sheets, at the both ends of which are attached the electrodes. D C supply is connected to the electrodes. The temperatures in heat conduction are analogous to voltages at corresponding points. Salt water filled in tank acts as conducting medium. The temperature drop corresponds to voltage drop & voltage with reference to one electrode is measured. The current through electrical circuit is analogous to flow of heat, Q and the electrical resistance corresponds to thermal resistance. By putting separators in the separators in the tank across the current (i.e. heat) flow, composite walls models can also be simulated, & thus conduction can be studied by relating electrical parameters to thermal parameters.
