Thermoelectric constant of a thermocouple are

\alpha

and

\beta .

. Thermoelectric power at inversion temperature is

View answer and explanation

Correct option: B

- \alpha

Option B (

- \alpha

) is correct because at the inversion temperature, the thermoelectric power is given by the derivative of the thermoelectric EMF with respect to temperature, evaluated at the inversion temperature, which results in

- \alpha
