  3. 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 ...

  4. 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.

  5. Fire-resistance rating - Wikipedia

    en.wikipedia.org/wiki/Fire-resistance_rating

    A fire-resistance rating typically means the duration for which a passive fire protection system can withstand a standard fire resistance test. This can be quantified simply as a measure of time, or it may entail other criteria, involving evidence of functionality or fitness for purpose.

  6. 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. [18]

  7. 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. [1]

  8. 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.

  9. Heat sink - Wikipedia

    en.wikipedia.org/wiki/Heat_sink

    The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:
