2. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the airplane while it is on the ground. Conversely, internal 400 Hz internal power may be converted to 50 Hz or 60 Hz for convenience power outlets available to passengers during flight.

3. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   A commonly used light in the home in the 1960s in 220–240 V countries was a circular tube ballasted by an under-run regular mains filament lamp. Self ballasted mercury-vapor lamps incorporate ordinary tungsten filaments within the overall envelope of the lamp to act as the ballast, and to partially compensate for the red-deficient light ...

4. Induction lamp - Wikipedia

   en.wikipedia.org/wiki/Induction_lamp

   The driver is connected to mains electricity, and is generally designed to operate on voltages between 100 and 277 VAC at a frequency of 50 or 60 Hz, or on a voltage between 100 and 400 VDC for battery-fed emergency light systems.

5. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   A very small low-power dummy load such as a ceramic power resistor or 10-watt light bulb can be attached to the supply to allow it to run with no primary load attached. The switch-mode power supplies used in computers have historically had low power factors and have also been significant sources of line interference (due to induced power line ...

6. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.

7. Mains electricity - Wikipedia

   en.wikipedia.org/wiki/Mains_electricity

   4 Includes small electric devices, heating elements, exterior lights, outdoor grills, pool and spa heaters, backup electricity generators, and motors not listed above. Does not include electric vehicle charging. Electronic appliances such as computers or televisions sets typically use an AC to DC converter or AC adapter to power the device ...

8. Motor–generator - Wikipedia

   en.wikipedia.org/wiki/Motor–generator

   These are motor/generators rather than motor–generators, single units which can act as either a motor or a generator. They make the cars more fuel-efficient by harvesting energy from regenerative braking and from the turbocharger, and can also be used to provide up to 160 BHP extra to the wheels to aid acceleration and overtaking, or to spin ...

9. Electric light - Wikipedia

   en.wikipedia.org/wiki/Electric_light

   An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting . Lamps usually have a base made of ceramic , metal, glass, or plastic which secures the lamp in the socket of a light fixture , which is often called a "lamp" as well.
