- the change in temperature of either junction of a thermocouple when a current is maintained in the thermocouple and after allowance is made for a temperature change due to resistance.
Origin of Peltier effect
1855–60; named after Jean C. A. Peltier (1785–1845), French physicist who discovered it

- physics the production of heat at one junction and the absorption of heat at the other junction of a thermocouple when a current is passed around the thermocouple circuit. The heat produced is additional to the heat arising from the resistance of the wiresCompare Seebeck effect
