  2. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    An intermediate switch can, however, be implemented by adding appropriate external wiring to an ordinary (six terminal) DPDT switch, or by using a separate DPDT relay. By connecting one or more 4-way (intermediate) switches in-line, with 3-way switches at either end, the load can be controlled from three or more locations.

  3. 3-way lamp - Wikipedia

    en.wikipedia.org/wiki/3-way_lamp

    A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

    Beside the TLM it was proposed the gated four-probe measurement [3] and the modified time-of-flight method (TOF). [4] The direct methods able to measure potential drop on the injection electrode directly are the Kelvin probe force microscopy (KFM) [ 5 ] and the electric-field induced second harmonic generation.

  5. Mass flow sensor - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_sensor

    A burn-off relay applies a high current through the platinum hot wire after the vehicle is turned off for a second or so, thereby burning or vaporizing any contaminants that have stuck to the platinum hot wire element. The hot film MAF sensor works somewhat similar to the hot wire MAF sensor, but instead it usually outputs a frequency signal.

  6. Overheating (electricity) - Wikipedia

    en.wikipedia.org/wiki/Overheating_(electricity)

    A fuse is a common type of circuit breaker that involves direct effect of Joule-overheating. A fuse is always placed in series with the path of current it will affect. Fuses usually consist of a thin strand of wire of definite-material. When more that the rated current flows through the fuse, the wire melts and breaks the circuit.

  7. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.

    LAPD officials say Kia and Hyundai vehicles made between 2010 and 2021 are manufactured in a way that makes them more susceptible to hot-wire, a shortcoming that has been exploited and shared on ...

  9. Hot-wiring - Wikipedia

    en.wikipedia.org/wiki/Hot-wiring

    Hot-wiring is the process of bypassing a motor vehicle's ignition switch and thus starting it without the key.It is often utilized during a vehicle theft. [1] However, a legitimate vehicle owner who has lost a vehicle key or starting a vehicle with inoperable ignition switch (e.g. in run-down old cars) may also use this process.
