I just did a thermoelectric generator from seebeck plate. And when temperature increases, the plate's resistance increases from 12 ohms to 8 M ohms. Why is that and how todeal with it??
Why does seebeck plate resistance increase due to temperature?

In summary, the conversation discusses a thermoelectric generator made from a Seebeck plate and the increase in resistance as temperature increases. The link provided offers information on dealing with this issue and clarifies that an ohmmeter cannot be used to test a TE module due to the Peltier and Seebeck effects. The use of an LCR meter is suggested instead. The link also includes visual aids for better understanding.

Related to Why does seebeck plate resistance increase due to temperature?
1. Why does temperature affect the resistance of a Seebeck plate?
Temperature affects the resistance of a Seebeck plate because it causes changes in the material's molecular structure. As the temperature increases, the atoms in the material vibrate more, creating more resistance for the flow of electricity.
2. How does the Seebeck effect contribute to the increase in resistance with temperature?
The Seebeck effect, also known as thermoelectric effect, is the phenomenon that occurs when a temperature difference between two dissimilar conductors creates a voltage difference. This voltage difference leads to a flow of current, which in turn increases the resistance of the Seebeck plate.
3. Is the increase in resistance due to temperature the same for all materials?
No, the increase in resistance due to temperature varies for different materials. The amount of resistance depends on the material's molecular structure, as well as its electrical and thermal conductivity properties.
4. Can the Seebeck plate resistance decrease with temperature?
Yes, it is possible for the resistance of a Seebeck plate to decrease with temperature. This can occur in materials with negative temperature coefficients, meaning their resistance decreases as temperature increases.
5. How does the Seebeck plate resistance affect the accuracy of temperature measurements?
The resistance of a Seebeck plate can affect the accuracy of temperature measurements as it can introduce errors in the measurement. This is why it is important to calibrate the Seebeck plate and account for its resistance when using it for temperature measurements.
