2 Electricity – Part D “Electrical Charge – Static”

Aims…

2.22P identify common materials which are electrical conductors or insulators, including metals and plastics

2.23P practical: investigate how insulating materials can be charged by friction

2.24P explain that positive and negative electrostatic charges are produced on materials by the loss and gain of electrons

2.25P know that there are forces of attraction between unlike charges and forces of repulsion between like charges

2.26P explain electrostatic phenomena in terms of the movement of electrons

2.27P explain the potential dangers of electrostatic charges, e.g. when fuelling aircraft and tankers

2.28P explain some uses of electrostatic charges, e.g. in photocopiers and inkjet printers.
