Question

First order derivation of thermo emf produced in thermo-couple with respect to temperature gives ........

• A. inversion temperature
• B. thomson coefficient
• C. neutral temperature
• D. thermoelectric power

Answer 1

Answer: (D)

thermoelectric power

Answer 2

First order derivation of thermo emf with respect to temperature $= \frac {dE}{dT}$
But we know that the thermoelectric power \hspace15mm P= \frac {dE}{dT}
So, the first order derivation of thermo emf produced in thermo-couple with respect to temperature gives thermoelectric power.
