With the cold junction at `0^(@)C` the neutral temperature for a thermo-couple is obtained at `270^(@)C`.
The cold junction temperature is now lowered to `-10^(@)C` Obta in the
(a) neutral temperature
(b) the temperature of inversion in this case.

Text Solution

Verified by Experts

(a) Neutral temperature remains same (i.e. `270^(@)C`)
(b) Temperature of inversion becomes
`T_(n)=(T_(0)+T_(1))/( 2)rArr 270=(-10+T_(1))/(2)rArrT_(1)=540+10=550^(@)C`
