Peltiérefektiin
Peltiérefektiin, often referred to as the Peltier effect, is a thermoelectric phenomenon. It occurs when an electric current is passed through a junction of two dissimilar conductors or semiconductors. In essence, it describes the absorption or liberation of heat at the junction of two different materials when an electric current flows through them. Specifically, if a direct current is applied, one junction will get cooler while the other gets warmer.
The magnitude of the temperature change is directly proportional to the current flowing through the junction
