The subsequent problems deal with the figure and table belowFor a Type J (Iron-Constantan) thermocouple configuration (as shown above) with a 0°C reference (Tref):where Vemf is the voltage difference produced by the junction pair (Vemf = VA ? VB in the figure).Assume that nodes A and B are at the same temperature, unless indicated otherwise. Assume that the op amp is ideal.If the top iron wire is disconnected from node A and an aluminum wire with uniform temperature (same as the temperature of node A) and negligible

resistance is attached between the loose end of the iron wire and node A (and everything else remains the same), what is the effect on Vout?

A. it changes
B. no effect
