  2. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    An LCDI cord has a fine wire mesh around the conductors, and circuitry to detect current leaking from the conductors to the mesh, which would happen if the cord were damaged or frayed. The plugs are normal NEMA 5-15, 5-20, 6-15, 6-20, or 6-30 plugs, depending on the air conditioner design, and are typically molded-on designs.

  3. Submarine power cable - Wikipedia

    en.wikipedia.org/wiki/Submarine_power_cable

    Alternating-current (AC) submarine cable systems for transmitting lower amounts of three-phase electric power can be constructed with three-core cables in which all three insulated conductors are placed into a single underwater cable. Most offshore-to-shore wind-farm cables are constructed this way.

  4. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

  6. AC motor - Wikipedia

    en.wikipedia.org/wiki/AC_motor

    An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field , and an inside rotor attached to the output shaft producing a second rotating magnetic field.

  7. Incandescent light bulb - Wikipedia

    en.wikipedia.org/wiki/Incandescent_light_bulb

    Luminous efficacy is measured in lumens per watt (lm/W). The luminous efficiency of a source is defined as the ratio of its luminous efficacy to the maximum possible luminous efficacy, which is 683 lm/W. [80] [81] An ideal white light source could produce about 250 lumens per watt, corresponding to a luminous efficiency of 37%. [82]

  8. War of the currents - Wikipedia

    en.wikipedia.org/wiki/War_of_the_currents

    The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...

  9. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply. Some graphics cards (especially multiple cards) and large groups of hard drives can place very heavy demands on the 12 V lines of the PSU, and for these loads, the PSU's 12 V rating is crucial.
