The Petlier coefficient of a thermo-couple of metls

A

and

B

at junction temperature

T

is given by

View answer and explanation

Correct option: B

T\frac{{dE}}{{dT}}

Option B (

T\frac{{dE}}{{dT}}

) is correct because the Peltier coefficient is defined as the product of the absolute temperature and the rate of change of the electromotive force (EMF) with respect to temperature.
