Q1a) A differential amplifier is used with a thermocouple sensor in a way shown in figure below. What values of R1 and R2 would give a circuit, which has an output of 10mV for a temperature difference between the thermocouple junctions of 100 C with a copper-constantan thermocouple if the thermocouple is assumed to have a constant sensitivity of 50μV/C (5 points) R₁ R₁ V Hot junction Cold junction R₂ out b) Design a summing amplifier circuit that can be used to produce an output that ranges from -1 to -10 v when the output goes from 0 to 200 m V (5 points)
