In a semi-conductor thermogenerator, the no-load voltage and the short-circuit current are measured as a function of the temperature difference. The internal resistance, the Seebeck coefficient and the efficiency are determined.
Tasks
To measure no-load voltage U0 and short-circuit current Is at different temperature differences and to determine the Seebeck coefficient.
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.
To determine the efficiency of energy conversion, from the quantity of heat consumed and the electrical energy produced per unit time.
What you can learn about
