THERMOCOUPLE
-
How Its works?? 
If the temperature of both the junctions is same, equal and opposite emf will be generated at both junctions and the net current flowing through the junction is zero
since the junction are maintaned at different temperatures the Peltier emf is generated within the circuit and it is the function of the temperatures of two junctions
the voltage or current output obtained from thermocouple circuit gives the value of unknowk temperature directly
