What is static electricity How can it be generated? Static electricity is generated by friction between two insulating materials. When the materials are rubbed together, electrons are removed from atoms within the materials, giving rise to a static electric charge. In practical electronics this source of electricity causes tremendous problems.
What are three ways we can generate static electricity?
- Contact – Whenever objects hit each other, electrons can be passed to or received from the surface of another object.
- Detachment – when one material is being separated from another material by peeling, electrons may not able to return back to the original molecule.
What is the main source of static electricity? The main causes of static electricity are: Contact and separation between two materials (including friction, travelling over rollers, etc) Rapid heat change (e.g. material going through an oven) High energy radiation, UV, X-ray, intense electric fields (not very common in industry)
What materials create the most static electricity?
|Materials that gain a positive (+) electrical charges (Tend to give up electrons)|
|Air||Greatest tendency for giving up electrons and becoming highly positive (+) in charge|
|Rabbit fur||Fur is often used to create static electricity|
|Glass||The glass on your TV screen gets charged and collects dust|
