Explain neutral and inversion temperatures with the help of a graph between the thermo emf and the temperature of the hot junction in a thermocouple.
The thermo emf of a thermocouple varies with the temperature theta of the hot junction as E=a theta +b theta square V Where the ratio of a and b is 700^°C. If
