  2. Backfeeding - Wikipedia

    en.wikipedia.org/wiki/Backfeeding

    A common source of unintentional backfeeding is an electrical generator (typically a portable generator) that is improperly connected to a building electrical system.A properly installed electrical generator incorporates the use of a transfer switch or generator interlock kit to ensure the incoming electrical service line is disconnected when the generator is providing power to the building.

  3. Bootleg ground - Wikipedia

    en.wikipedia.org/wiki/Bootleg_ground

    A receptacle with a bootleg ground. In building wiring installed with separate neutral and protective ground bonding conductors (a TN-S network), a bootleg ground (or a false ground) is a connection between the neutral side of a receptacle or light fixture and the ground lug or enclosure of the wiring device.

  4. Counter-electromotive force - Wikipedia

    en.wikipedia.org/wiki/Counter-electromotive_force

    For example, the voltage appearing across an inductor or coil is due to a change in current which causes a change in the magnetic field within the coil, and therefore the self-induced voltage.

  5. Breakdown voltage - Wikipedia

    en.wikipedia.org/wiki/Breakdown_voltage

    Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.

  6. Tip and ring - Wikipedia

    en.wikipedia.org/wiki/Tip_and_ring

    The voltage at a subscriber's network interface is typically 48 V between the ring and tip wires, with tip near ground (slightly negative relative to ground) and ring at -48 V relative to tip. In the middle 20th century, long loops in many rural areas of North America used range extenders, which operated at 100 or 130 volts to ensure reliable ...

  7. Wire bonding - Wikipedia

    en.wikipedia.org/wiki/Wire_bonding

    Wire bonding is a method of making interconnections between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Wire bonding can also be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another, although these are less common. Wire ...

  9. SMA connector - Wikipedia

    en.wikipedia.org/wiki/SMA_connector

    Reverse-polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification that reverses the gender of the interface, as shown in Figures 1 and 2. The term "reverse polarity" here refers only to the gender of the connector's contact pin, not in any way to the signal polarity.
