1. application
1.1. photocopier
1.2. Van de Graaff Generator
2. hazards
2.1. lightning
3. At it’s simplest, static electricity is an electrical charge that cannot move. It is created when two objects or materials that have been in contact with each other are separated
4. charges
4.1. like charges attract while unlike charges repel
5. electrically charging objects
5.1. methods
5.1.1. friction
5.1.1.1. rubbing one material with another, resulting in electrons moving from one surface to another
5.1.2. induction
5.1.2.1. A charged object is touched to the conductive material and some of the charge whether negative or positive is transfered
5.1.3. conduction
5.1.3.1. The uncharged conductive material is grounded on any neutrally-charged material and the charged object is held near it. The charge will flow between the two objects and the uncharged conductor will develop an opposite charge to the original charged object.
