A) \[310{}^\circ C\]
B) \[263{}^\circ C\]
C) \[265{}^\circ C\]
D) \[267{}^\circ C\]
E) \[270{}^\circ C\]
Correct Answer: E
Solution :
As per asked in question, clearly the temperature \[530{}^\circ C\] is the inversion temperature \[{{Q}_{i}}\] of couple. If \[{{Q}_{n}}\] be the neutral temperature and \[{{Q}_{c}}\] be the temperature of the cold junction, then \[{{Q}_{i}}-{{Q}_{n}}={{Q}_{n}}-{{Q}_{c}}\]\[\Rightarrow \] \[{{Q}_{n}}=\frac{{{Q}_{i}}+{{Q}_{c}}}{2}=\frac{530{}^\circ C+10{}^\circ C}{2}=270{}^\circ C\]
