Question

What is Seebeck Effect?

Answer

Seebeck Effect is: Seeback discovered in 1826 that an electric current could be produced by thermal means alone. When two dissimilar metals are connected and one of the junction is heated, there is a current in the circuit. This current is known as Thermo-Electric current. The emf developed in the circuit is called Thermo-Electric emf and is of the order of a few millivolt. This effect is called Seebeck Effect. The pair of metals constitutes a thermo-couple.
