  3. List of fire-retardant materials - Wikipedia

    en.wikipedia.org/wiki/List_of_fire-retardant...

    Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.

  4. Joule heating - Wikipedia

    en.wikipedia.org/wiki/Joule_heating

    Joule heating (also known as resistive heating, resistance heating, or Ohmic heating) is the process by which the passage of an electric current through a conductor produces heat.

  5. Fire resistance - Wikipedia

    en.wikipedia.org/wiki/Fire_resistance

    Fire resistance (ecology), a quality of plants that are harmed but not killed by fire; Fire retardant, a substance used to slow down or stop the spread of fire or reduce its intensity; Fireproofing, a passive fire protection method Fire-resistance rating, an indication of the ability for a passive fire protection system to withstand a standard ...

  6. Magnetoresistance - Wikipedia

    en.wikipedia.org/wiki/Magnetoresistance

    Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field.There are a variety of effects that can be called magnetoresistance.

  7. Flame retardant - Wikipedia

    en.wikipedia.org/wiki/Flame_retardant

    The amount of material consumed in the fire for the fire retardant (FR) tests was less than half the amount lost in the non-fire retardant (NFR) tests. The FR tests indicated an amount of heat released from the fire which was 1/4 that released by the NFR tests.

  8. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    An I–V curve, showing the difference between static resistance (inverse slope of line B) and differential resistance (inverse slope of line C) at a point (A).. The resistance between two terminals of an electrical device or circuit is determined by its current–voltage (I–V) curve (characteristic curve), giving the current through it for any given voltage across it.

  9. Passive fire protection - Wikipedia

    en.wikipedia.org/wiki/Passive_fire_protection

    Fire-resistance rated wall assembly with fire door, cable tray penetration and intumescent cable coating. Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement.
