The subsequent problems deal with the figure and table below
For 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 iron wire leads connected at A and B were switched (i.e., connect the lower iron wire to A instead of B and connect the upper iron wire to B
instead of A), the output Vout would? A. reverse sign B. oscillate wildly C. become zero D. not change E. become infinite
