  2. circuit containing two different metals, or
  3. semiconductors, by keeping the junctions
  4. between them at different temperatures.
  5. Discovered by the German physicist Thomas
  6. Seebeck (1770-1831), it is also called the
  7. thermoelectric effect, and is the basis of
  8. the thermocouple. It is the opposite of the

  10. a temperature difference between the
  11. junctions of different metals).
