effet Thomson

DEF: Effet thermoélectrique qui, dans un conducteur homogène parcouru par un courant et soumis à un gradient de température, provoque un transfert de chaleur.

DEF: A thermoelectric effect in which heat flows into or out of a homogeneous conductor when an electric current flows two points in the conductor at different temperatures, the direction of heat flow depending upon whether the current flows from colder to warmer metal or from warmer to colder.
CONT: ... the Thomson effect, is a voltage gradient which will appear along a conducting wire when a temperature gradient is set up along it.
