For a thermocouple , the inversion temperature is `600^(@)C`and the neutral temperature is `320^(@)C` . Find the temperature of the cold junction ?

Options

A. `40^(@)C`
B. `20^(@)C`
C. `80^(@)C`
D. `60^(@)C`

Answer

A

Explanation

Neutral temperature `T_(n) = (T_(c) + T_(i))/(2)`
`320^(@) = (T_(c) + 600^(@))/(2)`
`640^(@) = T_(c) + 600^(@)`
`T_(c) = 40^(@)C`
