- opposite charges attract
- like charges repel
- Three Ways to Charge an Object
- Contact
- Friction (steals electrons)
- Induction (charge without electrons)
Polarization:
- Coulomb's Law: the force between any two charges is inversely proportional to the distance
- Conductors: allows charges to move throughout an object
- Insulators: stop charges from passing through the object
(In the picture, you see the opposite charges attracting through polarization)
This process happens because:
- Opposite charges attract this a negative charged balloon attracts to the positive wall which enables it to now stick on the wall. It's all about the spreading of charges.
Voltage:
- Voltage is the charge difference over a unit of charge which is also known as the potential difference
