Static electricity, by Edwin Wong 4Sc3 by Mind Map: Static electricity, by Edwin Wong 4Sc3

1. Charges

1.1. Types of charge

1.1.1. Positve

1.1.2. Negative

1.2. SI unit

1.2.1. Coulomb (C)

1.3. Laws of electrostatics attraction

1.3.1. Like charges repel

1.3.2. Unlike charges attract

2. Charging

2.1. Rubbing

2.1.1. The atom that loses an electron is a postive ion while the atom that gains an electron is a negative ion.

2.1.2. Charging an object through the process of rubbing. When an object is rubbed, electrons from one object will transfer to the other object, charging it.

2.2. Induction

2.2.1. The process of producing electric charge on the urface of a conductor under the influence of an electric field.

2.2.2. Earthing process

2.2.2.1. Uses the earth to make positive or negative objects without the use of another object

3. Electric field

3.1. A region in which an electric charge experiences a force

3.2. Electric field lines

3.2.1. Path a positive charge would take if it is free to move

4. Applications of electrostatics

4.1. Hazards

4.1.1. Causes fires due to build up of electrons in an object

4.2. Conductive strip at the back of trucks containing flammable items

4.3. Photocopier

4.4. Electrostatic paint spraying

4.5. Electrostatic precipator

5. New node
