Charging Processes

• Electricity: A form of energy that can be carried away by wires and is used for heating and lighting and to provide power for machines.
• Electrical Charge: Is an electrical property of matter that creates force between the object.
• All matter is made out of atoms.
• Electricity originates inside an atom.
• An atom consists of subatomic particles. These are protons, electrons, and neutrons.
• Protons: Positive charge

  Electrons: Negative charge

  Neutrons: Neutral charge
• Objects are charged by gaining or loosing electrons.
• Only the electrons can transfer to objects because they're located outside the atom.
• Positive Charge: When electrons are transferred or an object looses an electron.
• Negative Charge: If the object gains or acquires electrons.
• Neutral Charge: When the object does not gain or loose electrons.
• Force of Attraction: A force that pulls objects together. Happens when opposite charges are near eachother.
• Force of Repulsion: A force that pushes objects apart from eachother. Happens when like charges are near eachother.
• Law of Charges: Opposite charges attract, and like charges repel.
• Charging by Friction: Can occur by rubbing two different materials.
• Triboelectric series: Is an arrangement of materials or substances according to their ability to gain or loose electrons.
• Charging by Conduction: Happens when electrons are transferred from one material to another by direct contact.
• Conductors: Materials that allow electrons to flow freely. Copper is mostly used and or is the best.
• Insulators: Materials that do not allow electrons to easily flow through them.
• Charging by Induction: Charging process where an object can be charged without actual contact with any other charged object.
