Learning Objectives

-- state that there are positive and negative charges and that charge is measured in coulombs

-- state that unlike charges attract and that like charges repel

--describe an electric field as a region in which an electric charge experiences a force

--draw the field of an isolated point charge and show understanding 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 2 isolated point charges

-- show understanding that electrostatic charging by rubbing involves a transfer of electrons

--describe experiments to show electrostatic charging by friction and induction

-- distinguish between electrical conductors and insulators and give typical examples of each

--*explain that charge Q is quantized i.e. Q = ne where e = 1.6 x 10-19 C

-- describe examples where electrostatic charging may be a potential hazard

-- describe an example of the use electrostatic charging e.g. photocopier, spraying of paint, electrostatic precipitator and laser printer
