When current flows through a conductor, heat is produced, this is
The temperature of a hot junction , at which the thermo emf is maximum is
Just, above (beyond) neutral temperature, thermo emf
The thermo electric power is the rate of change of thermo emf with
When different parts of a metal are kept at different temperature, and current is passed
Through it, the heat is either evolved or absorbed; this effect is
The plot showing the variation of thermo emf with temperature of the hot junction of a thermocouple is
