Enthalpy said:You still need to introduce different behaviours of different metals. In this first attempt, junctions of identical materials would give a current, which doesn't happen. More, the loop has two paths from hot to cold, which can't behave identically if you're to observe a current or voltage.
Beware also that electrons in a metal don't resemble a gas. For some properties maybe, for others not at all - for instance the heat capacity of a metal.
The Seebeck effect is a phenomenon where a temperature difference between two dissimilar conductors or semiconductors causes a voltage difference. This occurs due to the flow of electrons from the hotter material to the cooler material, creating a potential difference.
The Seebeck effect is caused by the thermal gradient between two materials, as well as the difference in their electrical conductivities. The transfer of heat causes the movement of electrons, creating a voltage difference.
Any conductive or semiconductive material can exhibit the Seebeck effect, but it is most commonly observed in metals and semiconductors. Some common examples include copper, iron, and silicon.
The Seebeck effect is used in thermocouples, which are devices that convert heat energy into electrical energy. These are commonly used in temperature measurements and can also be found in thermoelectric generators for power generation.
The magnitude of the Seebeck effect is affected by the temperature difference between the two materials, the materials' electrical conductivities, and the distance between the two materials. The type of material and the presence of impurities can also influence the effect.
