Instructions for how to make an electrical thermometer. The electrical thermometer works like this - the design consists of four resistors each made from about 40 meters of very thin copper wire. The electrical resistance of wire changes with temperature. It is this change in resistance that causes changes in voltage which can be measured, and allows the device to be used to measure temperature.
