Uses of Static Electricity
Static electricity has many uses. Two examples are:
Insecticide spraying
- Insecticide is given an electrostatic charge when it is released.
- The insecticide is then attracted to the earth so moves away from the sprayer.
- There is a repulsion between the droplets of insecticide which means the droplets don't clump together.
- This gives an even layer of insecticide on the ground.
Photocopying
- The areas to receive ink are positively charged and the ink is negatively charged, which ensures an even coat of ink in the right places.
