The general circuit for the working of thermocouple is shown in the figure 1 above. It comprises of two dissimilar metals, A and B. These are joined together to form two junctions, p and q, which are maintained at the temperatures T 1 and T 2 respectively. Remember that the thermocouple cannot be formed if there are not two junctions.
