peltier effect

noun Physics.

1. 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.

noun

1. 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
