Definitions for "Peltier effect"
The production or absorption of heat at the junction of two metals on the passage of a current. Heat generated by the passage of the current in one direction will be absorbed if the current is reversed.
Peltier effect is the absorption or generation of heat (depending on the current direction) which occurs when an electric current is passed through a junction between two materials.
the observable effect of a voltage generated by a temperature gradient in two wires of dissimilar metals joined at one end. See
