What is Thermal Resistance - Thermal Resistivity

WebThermal resistance is a function of the thickness and thermal conductivity of a fabric, and is a very important parameter from the viewpoint of thermal insulation, and is proportional to the fabric structure also. The original thickness measurements for the three fabrics were under relaxed conditions. WebAs Eq. 2 states, in order to calculate resistivity, it is necessary to know the contact area, sample thickness, and resistance of the sample. Resistance is determined by applying a current source to the sample, measuring the resultant voltage, and calculating resistance with Ohm’s Law. Test current, which must be kept low to avoid heating the ...
