description The utility model relates to a Joule's law demonstrator which is an integrated instrument for the demonstration experiment of the Joule's law. The utility model is characterized in that the Joule's law demonstrator is composed of three sets of alternative (special) electricity heat meters and a temperature testing pipe thereof, an adjusting valve (can be substituted by a three-way pipe), a substrate auxiliary triangle, an ammeter, shunt resistors, a time recorder and a Ruyi switch, wherein the temperature testing pipe, the time recorder and the substrate auxiliary triangle form a temperature testing and timing part. The utility model simplifies the structure and improves the method for making the alternative (special) electricity heat meters, the resistors thereof and the shunt resistors, and is suitable for mass production and favorable for experimental operation. The utility model is the novel Joule's law demonstrator.
