A) \[210{}^\circ C\]
B) \[540{}^\circ C\]
C) \[520{}^\circ C\]
D) \[209{}^\circ C\]
Correct Answer: C
Solution :
When there is no deflection, then this temperature is called inversion temperature. It is given by the relation \[{{\theta }_{n}}=\frac{{{\theta }_{i}}+{{\theta }_{c}}}{2}\] Where \[{{\theta }_{c}}\] is temperature of cold junction \[={{20}^{o}}C\] and neutral temperature \[{{\theta }_{n}}={{270}^{o}}C\] \[\therefore \] \[{{\theta }_{i}}=2{{\theta }_{n}}-{{\theta }_{c}}=540-20={{520}^{o}}C\]
