Elektronen: negatieve lading → -
Protonen: positieve lading → +

Die cirkel in cirkels zijn een atoom
5 elektronen en 4 protonen → negatief atoom
5 elektronen en 5 protonen → neutrale atoom
4 elektronen en 5 protonen → positieve atoom

Positieve (+) deeltjes bewegen niet. (blijft gelijk)
Negatief geladen: overschot aan elektronen
Positief geladen: tekort aan elektronen
Neutraal geladen: elektronen zijn gelijk aan protonen




Pvc = in de muur, niet uv-straling bestendig
Hotelier = buiten, wel uv-straling bestendig. (- lading)
Perspex = positieve lading

Statische elektriciteit (vast, niet bewegend)
Tegenpool = dynamisch

Elektroscoop (zien/kijken)
Elektro Kijken
→ wijzers positief elektrisch, middelste staafje is ook positief elektrisch

Stroom en spanning
