How does the seebeck effect work?
The Seebeck effect is the production of electricity using heat. When the ends of conductors that are at different temperatures are joined, a direct electric current flows.
The Seebeck effect is used in thermocouples. If two dissimilar metals conductors are joined and the two joints (junctions) are kept at different temperatures then a voltage is produced. This is dependant on the tyes of metals used and the temperature difference between the junctions. There is a reverse of the Seebeck effect called the Peltier effect where a current through the two different materials results in a temperature difference between the junctions.
The Seebeck effect is a phenomenon in which a temperature difference between two dissimilar electrical conductors or semiconductors produces a voltage difference between the two substances. When heat is applied to one of the two conductors or semiconductors, heated electrons flow toward the cooler one. If the pair is connected through an electrical circuit, direct current (DC) flows through that circuit.
