WebDescribe the three methods of electrification: 1.) Friction - One object is ________ against another 2.) Conduction/Contact - 2 objects touch to produce static discharge 3.) Induction - electrical fields acting on one another without contact rubbed How are conductors different from insulators? WebContact electrification is a phrase that describes a phenomenon whereby surfaces become electrically charged, via a number of possible mechanisms, when two or more objects come within close proximity of one another. When two objects are "touched" together, sometimes the objects become spontaneously charged. WebApr 5, 2024 · The electrification of particles embedded in a turbulent flow may cause hazards such as spark discharges but is also exploited in several industrial applications.
