Peltierefektiä
Peltierefektiä, also known as the Peltier effect, is a thermoelectric phenomenon where electric current passing through the junction of two dissimilar conductors causes a temperature change at that junction. Discovered by Jean Charles Athanase Peltier in 1834, this effect is the inverse of the Seebeck effect, which generates a voltage when there is a temperature difference between two conductors.
When an electric current flows from one material to another at their junction, heat is either absorbed
The magnitude of the Peltier effect is quantified by the Peltier coefficient, which relates the heat absorbed
The Peltier effect has found practical applications in various devices. Thermoelectric coolers (TECs), often called Peltier
