  2. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

  3. North American Charging System - Wikipedia

    en.wikipedia.org/wiki/North_American_Charging_System

    The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International. [1] Developed by Tesla, Inc., it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022.

Tomonobu Otsu is the current President Director and Rachmat Gobel is the current President Commissioner. It is a joint venture between Panasonic Corporation Japan and ...

  5. Patch cable - Wikipedia

    en.wikipedia.org/wiki/Patch_cable

    A patch cord cable differs from a standard structured cabling in that a patch cable is stranded for flexibility, whereas a standard cable is solid copper. Because the patch cord is stranded copper construction the attenuation (signal loss) is higher on patch cords than solid cable so short lengths should be adhered to. [1]

  6. Copper conductor - Wikipedia

    en.wikipedia.org/wiki/Copper_conductor

    Electrical conductivity is a measure of how well a material transports an electric charge.This is an essential property in electrical wiring systems. Copper has the highest electrical conductivity rating of all non-precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C.

  7. Electrical termination - Wikipedia

    en.wikipedia.org/wiki/Electrical_termination

    Transmission line cables require impedance matching to carry electromagnetic signals with minimal reflections and power losses. The distinguishing feature of most transmission line cables is that they have uniform cross-sectional dimensions along their length, giving them a uniform electrical characteristic impedance. Signal terminators are ...

  8. Transatlantic communications cable - Wikipedia

    en.wikipedia.org/wiki/Transatlantic...

    When the first transatlantic telegraph cable was laid in 1858 by Cyrus West Field, it operated for only three weeks; a subsequent attempt in 1866 was more successful. [citation needed] On July 13, 1866 the cable laying ship Great Eastern sailed out of Valentia Island, Ireland and on July 27 landed at Heart's Content in Newfoundland, completing the first lasting connection across the Atlantic.

  9. Electrical conduit - Wikipedia

    en.wikipedia.org/wiki/Electrical_conduit

    Electrical conduit provides very good protection to enclosed conductors from impact, moisture, and chemical vapors. Varying numbers, sizes, and types of conductors can be pulled into a conduit, which simplifies design and construction compared to multiple runs of cables or the expense of customized composite cable.
