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.

What is Seebeck effect 12th physics?

Seebeck effect, production of an electromotive force (emf) and consequently an electric current in a loop of material consisting of at least two dissimilar conductors when two junctions are maintained at different temperatures. ... The German physicist Thomas Johann Seebeck discovered (1821) the effect.

What is Seebeck effect give an example of it?

The Seebeck effect occurs when the two ends of a thermocouple are at different temperatures, which results in electricity flowing from the hot metal to the cold metal. In the Peltier effect, a temperature difference is created between the junctions when electrical current flows across the terminals.
