2. Improper junction temperatures. A K-type thermocouple measures temperature T1 and has reference Tr as shown in Figure. Calculate the reading of the voltmeter under the following conditions:a. T1 = 100°C, Tr = 0°C, and the junctions x–x’ and y–y’ are each in their own temperature zones. (c = chromel, a = alumel).b. T1 = 100°C, Tr = 0°C, and junctions y–y’ are in a temperature zone. The junctions x–x’ are not in a temperature zone with a temperature difference of 5°C (x is at the higher temperature).c. Which reading is correct and what is the error in temperature using theincorrect reading?
