Lutz-Kelvin equation

The Lutz-Kelvin equation describes how certain materials, especially metals and alloys, change their electrical resistance when their temperature varies. As temperature increases, atoms in the material vibrate more, making it harder for electrical electrons to flow smoothly, which raises resistance. Conversely, cooling the material reduces atomic vibrations, decreasing resistance. This relationship helps engineers design devices that rely on precise temperature control, such as thermometers or electronic components, by predicting how resistance will change with temperature. The equation offers a mathematical way to estimate resistance variations, enabling better system stability and performance.
