What is the Seebeck Effect?

What is the Seebeck Effect?The principle of the thermocouple was first described by Seebeck in 1821. Seebeck discovered that when wires of two dissimilar metals were joined together to form a circuit of at least two junctions, a current would flow when the junctions were at different temperatures. This phenomenon, called the Seebeck Effect, is the basis upon which thermocouples are designed.
