The Seebeck effect is the production of electric voltage in a conductor which is kept under a temperature gradient.
If an applied temperature gradient ΔT produces an electric voltage of ΔV, then the ratio of ‘voltage produced’ to the ‘temperature difference’ is defined as the Seebeck coefficient (S) or thermopower of the conductor.
where P is the Peltier coefficient.

In Peltier effect, heating or cooling of a junction made up of two dissimilar conductors occurs when an electric current flows through it.
The rate of heat (dQ/dt) absorbed or evolved at a junction is proportional to the current flow in the circuit I. The effect is defined as follows,
