It is made of two dissimilar metals that are joined together at one end. When the two metals are heated, an electric current is generated. The amount of current generated is proportional to the temperature difference between the two metals.<\/p>\n<p>Thermocouples are used in a variety of applications, including temperature measurement, temperature control, and power generation.<\/p>\n<p>B.
