Q. The neutral temperature of a thermocouple is $350℃$ when the cold junction is at $0℃.$ When the cold junction is immersed in a bath of $30℃,$ the inversion temperature is
A) $700℃$
B) $600℃$
C) $350℃$
D) $670℃$
Explanation
(d) $t_{i} = 2t_{n} - t_{c} \Rightarrow t_{i} = 2 \times 350 - 30 = 670℃$
