WebApr 30, 2024 · Going for graphite. The search for a material with higher resistivity than stainless steel led Cressall to develop a resistor using graphite, such as that traditionally used in vacuum furnace elements. The graphite is poured into the ceramic tiles and heated to over 400˚C, which dries the material into a solid structure.
WebBegin by sketching a rectangular resistor on a blank sheet of paper using one of the graphite sticks. The rectangle should be at least 1cm in width, and should be as thick as you can get it with the graphite stick (try to have consistent thickness throughout).
