Thermocouples > 10 - Intermediate Metals Law
The algebraic sum of the thermal emfs in a circuit composed of any number of different metals is zero if the entire circuit is at the same temperature”. It follows that in a thermoelectric circuit composed of two different metals, the emf produced will not change when a generic metal is inserted at any point in the circu
it, as long as the new junctions are kept at the same temperature.
An example of the practical application of this law is the use of brass or copper contacts to connect the thermocouple to the extension cable in the head.
Where he concludes, then, that: T3=T4
E1=E2
