Electrical heat generation equation
WebHeat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius (∘ C ^\circ\text C ∘ C … A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect (a form of thermoelectric effect). Thermoelectric generators function like heat engines, but are less bulky and have no moving parts. However, TEGs are typically more expensive and less efficient.
