Gr 9 Electricity Tes
| Term | Definition |
|---|---|
| Law of Electrical Charge | A charge that is similar(positive and positive)repels and charges that are different(positive and negative) attract. |
| Electrostatic Serise | The object that is closer to the bottom of the electrostatic serise gains electron(becomes -)the object that is closer to the top loses electron(becomes +) |
| Friction | 2 neutral objects (different materials) are rubbed together. Electrons move. Finish with one+ve and one-ve object(based on the electrostatic series) |
| Conduction | 2 objects(at least one is charged)make contact with each other. Electrons move from one object to the other. After contact, the two objects will have the same type of charge. |
| Induction(temporary) | A charged object is brought close to ( not touching) a neutral metal electroscope. Electrons are not transferred, but move with in the electroscope. |
| Induction(permanent) | Some method as charging by induction(temporary) but you ground the neutral electroscope with your hand, then remove it. |
| Grounding | Connecting an object to a large body, like the Earth, that is capable of effectively removing an electric charge that the object might have. |
| Benefits of Fossil Fuels |
