  2. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    An electric heater is an electrical device that converts an electric current into heat. [1] The heating element inside every electric heater is an electrical resistor , and works on the principle of Joule heating : an electric current passing through a resistor will convert that electrical energy into heat energy.

  3. Thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_generator

    A thermoelectric generator (TEG), also called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect [1] (a form of thermoelectric effect).

  4. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    The electricity is then converted into light energy by the electrical arc (electrode efficiency and discharge efficiency). The light is then transferred to a fluorescent coating that only absorbs suitable wavelengths, with some losses of those wavelengths due to reflection off and transmission through the coating (transfer efficiency).

  5. Energy transformation - Wikipedia

    en.wikipedia.org/wiki/Energy_transformation

    Thermal energy of the exhaust gases converted into thermal energy of steam through heat exchange Kinetic energy of steam converted to mechanical energy in the turbine Mechanical energy of the turbine is converted to electrical energy by the generator, which is the ultimate output

  6. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating. Heating elements are used in household appliances, industrial equipment, and scientific ...

  7. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    The two modes of energy transfer, as heat and by electric current, can be distinguished when there are three distinct bodies and a distinct arrangement of surroundings. But in the case of continuous variation in the media, heat transfer and thermodynamic work cannot be uniquely distinguished. This is more complicated than the often considered ...

  8. Joule heating - Wikipedia

    en.wikipedia.org/wiki/Joule_heating

    Joule heating (also known as resistive, resistance, or Ohmic heating) is the process by which the passage of an electric current through a conductor produces heat.. Joule's first law (also just Joule's law), also known in countries of the former USSR as the Joule–Lenz law, [1] states that the power of heating generated by an electrical conductor equals the product of its resistance and the ...

  9. Electrical energy - Wikipedia

    en.wikipedia.org/wiki/Electrical_energy

    Electric utilities measure energy using an electricity meter, which keeps a running total of the electric energy delivered to a customer. Electric heating is an example of converting electrical energy into another form of energy, heat. The simplest and most common type of electric heater uses electrical resistance to convert the energy. There ...
