The cold junction of a thermocouple is maintained at `15^(@)C`. No thermo-emf is developed when the hot junction is mainted at `525^(@)C` . Find neutral temperature.

Text Solution

Verified by Experts

Since `E=0` then
`T_(i) = 525^(@)C`
`T_(c) = 15^@C`
`T_(i) - T_(n) = T_(n)-T_(c)`
`T_(n) = (T_(i)+T_(c))/(2) = (525+15)/(2) = 270^@C`.
