Thermoelectric power generators are the devices which used to convert temperature difference between two junctions into electrical energy. A working of thermoelectric generator is based on Seebeck effect.  According to which, a loop of two dissimilar metal develops an emf when the two junctions are kept at different temperature. That is why it is also referred as Seebeck … Read more DMPQ-Explain the concept of functioning of Thermoelectric Generator.
