- Many everyday items use static electricity to work, these include:
1 of 5
Electrostatic paint sprayer
- The nozel of the paint sprayer is posatively charged and the metal pannel is negatively charged.
- The pannel attracts paint droplets and the droplets repel each other, spreading out and covering the object in paint.
2 of 5
- The drum of a photocopier is charged.
- This then lowered as it is exposed to light.
- Light reflects off the paper but the areas of black do not reflect so those areas of the drum stay charged.
- The balck toner sticks to the drum where it is still charged and is then pressed onto the paper.
- The paper is then heated to stick the toner to it permanently.
