• # question_answer The neutral temperature of a thermocouple is $300{}^\circ C$. What is the inversion temperature, if the temperature of cold junction is$10{}^\circ C$? A)  $590{}^\circ C$          B)  $610{}^\circ C$ C)  $310{}^\circ C$          D)  $290{}^\circ C$

From the relation ${{T}_{i}}=2{{T}_{n}}-{{T}_{0}}$ Given,   ${{T}_{n}}=300{}^\circ C,{{T}_{0}}=10{}^\circ C$ $\therefore$ ${{T}_{i}}=2\times 300-10$ ${{T}_{i}}=600-10$ ${{T}_{i}}=590{}^\circ C$
