Explanation:- Thermoelectric effect also called as seeback effect. 


Principle: When two dissimilar metals are connected with each other at their ends a thermocouple junction is formed. This thermocouple junction formed between them when kept at different temperatures, An EMF is generated this EMF is known as Thermoelectric emf. This thermoelectric emf will force a continuous current this current is known as thermoelectric current and the whole phenomenon is called as thermoelectric effect or Seeback effect.


Applications:- 1. Measurement of the temperature difference between two objects. 2. Used in the thermoelectric generator, these functions like a heat engine. 3. Used in power plants for converting waste heat into additional power (a form of energy recycling). 4. In automobiles as automotive thermoelectric generators (ATGs) for increasing fuel efficiency. 5. Space probes often use radioisotope thermoelectric generators with the same mechanism but using radioisotopes to generate the required heat difference.
