Students should be able to:
- state that there are positive and negative charges and that charge is measured in coulombs
- state that unlike charges attract and like charges repel
- describe an electric field as a region in which an electric charge experiences a force
- draw the electric field of an isolated point charge and recall that the direction of the field lines gives the
direction of the force acting on a positive test charge
- draw the electric field pattern between two isolated point charges
- show an understanding that electrostatic charging by rubbing involves a transfer of electrons
- describe experiments to show electrostatic charging by induction
- describe examples where electrostatic charging may be a potential hazard
- describe the use of electrostatic charging in an electrostatic precipitator and apply the use of electrostatic
charging to new situations.
