WebIf heat is proportional to resistance, then why do higher (a kilo) resistance can't create much heat in a circuit? heat is not proportional to resistance. Heat is proportional to power. With fixed voltage sources, HIgher resistance leads to lower current and less power ergo, less … Answer (1 of 6): I hope, you mean “thermal resistance” to heat transfer. Just a sm… WebFeb 8, 2012 · Most heating elements use Nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time." Feb 8, 2012 #4 willem2 2,109 371

WebJan 26, 2024 · Steel alloys can be highly heat-resistant. The aerospace, automotive and construction industries use this material to create specific parts such as pressure vessels or boilers. 4) Niobium (Nb) – Formerly called Columbium (Cb), niobium is used in steel alloys and has hardness characteristics similar to titanium (and ductility similar to iron). WebJun 21, 2024 · Heatsink thermal resistance is quoted in K/W or °C/W. For example, the temperature of a heatsink with a 10 °C/W rating will rise 10°C above ambient air for every watt it has to dissipate. In general, larger heatsinks will have lower thermal resistance and will keep the devices cooler. canada post conception bay south
