2. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   The Kelvin color temperature scale ranges from 1000K (amber) to 3000K (yellow) to 5500K (white) to 8000K (blue) to 12000K (purple). HID Lamp Color Temperature Range HID lamps produce different colors of light primarily through the use of various metal additives in the lamp's arc tube and the physics of the gas discharge process.

3. Headlamp - Wikipedia

   en.wikipedia.org/wiki/Headlamp

   HID projector low beam headlamp illuminated on a Lincoln MKS. High-intensity discharge lamps (HID) produce light with an electric arc rather than a glowing filament. The high intensity of the arc comes from metallic salts that are vaporized within the arc chamber. These lamps have a higher efficacy than tungsten lamps.

4. SAE J1772 - Wikipedia

   en.wikipedia.org/wiki/SAE_J1772

   SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".

5. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   A high-intensity discharge (HID) lamp is a type of electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. Compared to other lamp types, relatively high arc power exists for the arc length.

6. Sodium-vapor lamp - Wikipedia

   en.wikipedia.org/wiki/Sodium-vapor_lamp

   6 Na + Al 2 O 3 → 3 Na 2 O + 2 Al. As a result, these lamps can be started at a relatively low voltage, but, as they heat up during operation, the internal gas pressure within the arc tube rises, and more and more voltage is required to maintain the arc discharge. As a lamp gets older, the maintaining voltage for the arc eventually rises to ...

7. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   A generator can also be driven by human muscle power (for instance, in field radio station equipment). Protesters at Occupy Wall Street using bicycles connected to a motor and one-way diode to charge batteries for their electronics [22] Human powered electric generators are commercially available, and have been the project of some DIY ...

8. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   The primary coil in the charger induces a current in the secondary coil in the device being charged. Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power ...

9. Arc lamp - Wikipedia

   en.wikipedia.org/wiki/Arc_lamp

   The tendency of electric arcs to flicker and hiss was a major problem. In 1895, Hertha Ayrton wrote a series of articles for The Electrician , explaining that these phenomena were the result of oxygen coming into contact with the carbon rods used to create the arc.
