As the temperature of hot junction increases, the thermo e.m.f.

As the temperature of hot junction increases, the thermo emf :

Assertion : When temperature of cold junction of a thermocouple is lowered, the value of neutral temperature of this thermocouple is raised. Reason : When the difference of temperature of two junction is raised, more thermo e.m.f. is produced.

A thermo couple is formed by two metals X and Y metal X comes earlier to Y in Seebeck series. If temperature of hot junction increases beyond the temperature of inversion. Then direction of current in thermocouple will so

If the temperature of hot junction is increased beyond inversion temperature then the thermo emf

The temperature of the cold junction of thermo-couple is 0^(@)C and the temperature of hot junction is T^(@)C . The e.m.f . is E=16T-0.04 T^(2)mu volts. The temperature of inversion is

The temperature of the cold junction of thermo-couple is 0^(@)C and the temperature of hot junction is T^(@)C . The e.m.f . is E=16T-0.04 T^(2)mu volts. The temperature of inversion is
