Peltierefekti
The Peltier effect is a thermoelectric phenomenon discovered by Jean Charles Athanase Peltier in 1834. It describes the phenomenon where a temperature change occurs when an electric current is passed through the junction of two different conductors. Specifically, if an electric current flows in one direction across the junction, heat is absorbed, causing cooling. If the current is reversed, heat is released, causing warming. This is in contrast to the Seebeck effect, which generates an electric current from a temperature difference.
The magnitude of the heating or cooling effect depends on the current, the properties of the materials
Practical applications of the Peltier effect are found in thermoelectric coolers (TECs), also known as Peltier
