Thermoelectricity occurs when a temperature difference across a material generates an electric voltage, a phenomenon known as the Seebeck effect. This happens because charge carriers (electrons or holes) in the material move from the hot side, where they have higher energy, to the cold side, creating a potential difference. Conversely, applying an electric current can create a temperature difference through the Peltier effect. Thermoelectric materials are often used in applications such as power generation and cooling systems due to their ability to convert heat directly into electricity and vice versa.

Why do you need two metals to conduct electricity?
Using two different metals creates a potential difference or voltage between them, which allows the flow of electrons to generate an electric current. This process is known as the Seebeck effect in thermoelectricity and is utilized in devices such as thermocouples to measure temperature differentials.

What is Thermoelectricity?
Thermoelectricity is electricity generated with the thermoelectric effect. Essentially, when you heat one end of a suitable material, the electrons move away from the heat, creating an electric current. It is not terribly efficient, but thermoelectric generators are often used to capture waste heat. It can also refer to electricity produced by a thermoelectric power plant, where heat (usually in the form of steam) from burning some material, usually one of the fossil fuels (coal, oil and natural gas), but also biomass, biogas, or even garbage, generates electricity.

What is the relationship between thermal energy and electric fields?
Thermal energy and electric fields are related through the concept of thermoelectricity. When there is a temperature difference in a material, it can create an electric field, which can then generate an electric current. This phenomenon is known as the Seebeck effect. In essence, thermal energy can be converted into electrical energy through the interaction of temperature gradients and electric fields.
