About This Product
With ice water on one side and hot water on the other, the temperature difference across the module drives a current: students first read the open-circuit voltage, then switch to the motor and watch the propeller turn. Logging voltage as the hot water cools gives a graph of voltage against temperature difference for the Seebeck effect.
Frequently Asked Questions
Does the Thermocouple Electricity Generator STEM Lab need batteries?
No. All the electrical energy comes from the temperature difference between the hot and cold reservoirs across the thermoelectric module.
What happens if both tanks hold water at the same temperature?
With no temperature difference across the module, no voltage is produced.
