Benefits

• Open design allows to fully understand function and applications
• Individual instruments for distinct functions (no “black box”)
• Key products of the experiment setup can also be used for investigating the Peltier effect

Tasks

1. To measure no-load voltage U0 and short-circuit current Is at different temperature differences and to determine the Seebeck coefficient.
2. To measure current and voltage at a constant temperature difference but with different load resistors, and to determine the internal resistance Ri from the measured values.
3. To determine the efficiency of energy conversion, from the quantity of heat consumed and the electrical energy produced per unit time.
