Thank you to https://edulab.com/van-de-graff-generator-how-does-it-work/ for the above image it is very much appreciated.

  1. What does a charged object create around itself?
  2. Where is the electric field the strongest?
  3. Where is the electric field the weakest?
  4. What is experienced when a second object is placed in the field.
  5. What happens to the forces if the distance between the two objects is decreased?
  6. Can you draw the electric field pattern for an isolated charged sphere? See diagram below

Required Practicals for AQA GCSE Physics Electricity

Here I have linked to popular youtube videos that cover these practicals perfectly

Required practical activity 4: use circuit diagrams to construct appropriate circuits to investigate
the I–V characteristics of a variety of circuit elements, including a filament lamp, a diode and a
resistor at constant temperature.

Required practical activity 3: Use circuit diagrams to set up and check appropriate circuits to
investigate the factors affecting the resistance of electrical circuits. This should include:
• the length of a wire at constant temperature
• combinations of resistors in series and parallel.

Static Electricity Revision questions for AQA GCSE Physics

Questions on Static Electricity

  1. What happens to certain insulating materials that are rubbed against each other?
  2. What is rubbed off one material and onto the other?
  3. What happens to the material that gains the negative charge?
  4. What happens to the material that loses the negative charge?
  5. What happens when two electrically charged objects are brought close together?
  6. What can you say about the force when the two objects carry the same type of charge?
  7. What can you say about the force when the two objects carry different types of charge?
  8. Are attraction and repulsion a contact of a non-contact force?
  9. How does sparking occur?
