  • Insulators charged by friction -when two insulators move relative to each other, friction between the two can result in both objects becoming electrically charged -one of the objects becomes positively charged and other is negatively -eg plastic being rubbed against duster -conductors can become charged but will only retain that charge of they are insulated from their surroundings. If not insulated, then any charge that builds up will leak away Charging by induction it's possible for objects t...

  • What causes the accumulation of charge? Describe the types of materials that can gain charge How can one 'charge ' an object? -The gain or loss of electron -Insulators -Through friction Like charges... Repel Unlike charges... Attract Hazards of static electricity -Static electricity can build up in clouds. This causes lightning - a flow of charge through the atmosphere -It is dangerous when there are flammable gases or a high concentration of oxygen. A spark could ignite the gases and cause...

  • Know and understand that insulators can be charged by friction When two insulators move relative to each other, friction between the two can result in both objects becoming electrically charged. One of the objects becomes positively charged, and the other becomes negatively charged. Charging by Induction When a neutral object is places near to a charged object, the object can become charged. If one end of an object charged by induction is momentarily earthed, the charge leaks away, and the obje...
