O-Level Static Electricity

What the O-Level syllabus expects for Static Electricity, and how to practise it.

What the syllabus expects

State that charges come in positive and negative kinds and are measured in coulombs.
State that unlike charges attract while like charges repel.
Describe an electric field as a region where an electric charge feels a force.
Draw the electric field of a single isolated point charge and recall that the field-line direction shows the direction of the force on a positive test charge.
Draw the field pattern between two isolated point charges.
Understand that electrostatic charging by rubbing works through the transfer of electrons.
Describe experiments demonstrating electrostatic charging by induction.
Describe cases where electrostatic charging can pose a hazard.
Describe how electrostatic charging is used in an electrostatic precipitator and apply the idea to unfamiliar situations.
