Physics 1.0 / 5 based on 1 rating ? PhysicsElectricityGCSEAll boards Created by: RachaelCreated on: 19-04-08 20:25 Using electrostatics Many everyday items use static electricity to work, these include: 1 of 5 Electrostatic paint sprayer The nozel of the paint sprayer is posatively charged and the metal pannel is negatively charged. The pannel attracts paint droplets and the droplets repel each other, spreading out and covering the object in paint. 2 of 5 The photocopier The drum of a photocopier is charged. This then lowered as it is exposed to light. Light reflects off the paper but the areas of black do not reflect so those areas of the drum stay charged. The balck toner sticks to the drum where it is still charged and is then pressed onto the paper. The paper is then heated to stick the toner to it permanently. 3 of 5 Electrostatic hazards For example if a fuel pipe becomes charged it could then spark and cause and explosion. 4 of 5 Summary A spark froma charged object can make powder grains or certain gasses explode. To eliminate static electricity: use anti-static materials and earth metal objects. 5 of 5
