Question

Peltier coefficient of the junction of a pair of metals is proportional to

• A. absolute temperature of junction $T$
• B. square of absolute temperature of junction
• C. $\frac{1}{T}$
• D. $\frac{1}{T^2}$

Answer 1

The correct option is A absolute temperature of junction $T$

We know that Peltier coefficient, $\Pi =T\frac{d\epsilon }{d\theta }$

where $T=$ absolute temperature and $\frac{d\epsilon }{d\theta }=$ thermoelectric power.
so, $\Pi \propto T$
