By using our wire calculator, you agree to hold us harmless and you understand that this calculator is merely a guide and help, but not an absolute authority, therefore we recommend you have a professional or an engineering company perform the calculations in your application. Calculate overall heat transfer inclusive convection ; k - thermal conductivity (W/(mK), Btu/(hr o F ft 2 /ft)). an excellent source for quality material, competitive pricing and dependable service. 77 ohm per metre. Heat flow can be further classified as conduction, convection or radiation. They are made from a small cylinder of graphite, surrounded by a protective plastic coating. Resistance wire is designed to resist the flow of electricity which turns electrical energy into heat. The deviation is almost always toward more rather than less desired resistance. Nichrome is wound in coils to a certain electrical resistance, and current is passed through it to produce heat. Resistance is measured in ohms, Ω, and the resistance of a component can be found using an ohmmeter.
