Static Electricity: Electric Fields

Electric FieldRegion of space in which electric charges at rest experience an electrostatic force

Electric Field Line The line along which a positive charge would move if placed in the electric field Electric field lines can be demonstrated by sprinkling semolina on a container of cooking oil and running an electric current through two metal plates in the container The semolina will form parallel lines between the plates showing the electric field pattern 

Electric Field Strength Force per unit charge at a point in an electric field F/Q Unit: Newton per coulomb or volt per metre
