Question

A pure lead bar 10 cm long is maintained with one end at T=300 K and the other at 310 K. The thermoelectric potential difference thus induced across the ends is 12.8 ????V. Find the thermoelectric power for lead in this temperature range

Answer 1

Answer:1.28v/k

Explanation:

Thermoelectric power is the same as Seebeck coefficient.

So the formula is S =Vemf/Th - Tl

= 12.8/310-300

S= 12.8/10

=1.28V/T
