| Demonstrates: As an example of thermal energy being converted to electrical energy, thermoelectric current is observed. |
| Description: A temperature difference between two ends of a conductor results in a potential difference between the two ends. The size and polarity of the potential difference depends on the type of metal. A thermocouple is formed when two dissimilar metals are joined at one end. When the joined end is kept at a different temperature from the open ends, a potential difference is maintained between the open ends. This potential difference can be used to drive current through a galvanometer.
