WebJul 1, 2024 · Hyperphysics lists the resistivity, ρ, of graphite at 3 to 60 x 10 5 Ωm depending on impurities. I think you will have to go with your measured values but you need to be careful in case the resistivity drops dramatically as it heats up. (The current might rise beyond what your power supply can handle.) Share Cite Follow edited Jul 1, 2024 at 18:10 WebApr 16, 2024 · Thermal grease issues. Thermal conduction sheet Graphite TIM. ① Thermal resistance variation due to voids. Absorbs differences in level through its high compressibility, achieving a stable thermal resistance equivalent to that of thermal greases. ② Increase in thermal resistance due to the dryout phenomenon.
