Law of intermediate metals
WebThe law of intermediate metals states that the voltage reading, V 1-2 does not change if one adds a third (intermediate) wire in line with any of the wires in the circuit, as sketched below: In the above diagram, it is assumed that both of the new junctions (between metal B and metal C) are at the same temperature, i.e. ambient temperature, T a.

WebThe law of intermediate metals indicates the involvement of a third component won't interfere with the TC reading, provided that temperature is locally uniform. – Dan Jun 11, 2015 at 16:05 @Dan - Will W answered your question suggesting a spot welder. Out of curiosity, why did you not accept his answer and then leave this as a comment? – CBRF23 WebThe wires of the voltmeter will form further thermocouple junctions where they are attached (T3, T4). If both these additional junctions are at the same temperature (it does not matter exactly what temperature), then the “Law of Intermediate Metals” states that they will make no net contribution to the total EMF of the system.
