How can the properties of fields be understood using both an algebraic approach and a visual representation?
What are the consequences of interactions between electric and magnetic fields?
How are electric and magnetic fields like gravitational fields?
What are the relative strengths of the four fundamental forces?

Charge is quantized. Which other physical quantities are quantized? (NOS)
the direction of forces between the two types of electric charge
Coulomb’s law for charged bodies treated as point charges
the conservation of electric charge
Millikan’s experiment as evidence for quantization of electric charge
that the electric charge can be transferred between bodies using friction, electrostatic induction and by contact, including the role of grounding (earthing)
the electric field strength as given by E = F/q
electric field lines
the relationship between field line density and field strength
