For a thermocouple, `T_(c ), T_(n) " and " T_(i)` denote the temperatures of cold junction, the neutral temperature and the temperatures of inversion respectively. Which one of the following relation is correct ?

Options

A. ` T_(i)=(T_(c )+T_(n))/(2)`
B. `T_(i)2T_(n)-T_(c )`
C. `T_(i)=(T_(n)-T_(c ))/(2)`
D. `T_(i)=T_(n)-T_(c )`

Answer

B

Explanation

`T_(1)-l_(n)=l_(n)-l_(c )`
` 2T_(n)=T_(i)+T_(c ) implies T_(i)=2T_(n)-T_(c )`
