the duration of time for which the current is passed through thermocouple

Vedclass · Answer

(D) The total electromotive force $(emf)$ produced in a thermocouple is determined by the Seebeck effect,which depends on the nature of the metals used (Seebeck coefficients),the temperatures of the hot and cold junctions,and the Thomson coefficients of the metals. It is an instantaneous phenomenon related to the temperature gradient and material properties. Therefore,the total $emf$ does not depend on the duration of time for which the current is passed through the thermocouple.
