P2.2 Uses and dangers of static electricity
- electrostatic phenomena can be cuased through eveyday object: walking, touching door knobs, chairs ect.. this is due to the fact electrons flow between you and and an object heading towards earth. Static can build up in clouds, cauing huge sparks between the cloud and the ground: lightining.
-Earthing ~ electrons move from you to earth through the object one way or another.
