Uniform Electric Fields
When two parallel metal plates are given opposite charges and placed facing each other, the electric field between them is uniform — the field lines are parallel, evenly spaced, and perpendicular to the plates.
- The field points from the positive plate to the negative plate
- The field is the same strength everywhere between the plates
- Outside the plates, the field is very weak and can be ignored
This higher tier covers Higher Tier: Uniform Electric Fields within Static Electricity for GCSE Physics. Revise Static Electricity in Electricity for GCSE Physics with 15 exam-style questions and 12 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 12 of 15 in this topic. This section is most useful once the core foundation idea is secure, because it adds the detail that pushes answers higher.
Practice questions for Static Electricity
When a plastic rod is rubbed with a cloth, the rod becomes negatively charged. Which statement best explains why?
Explain why a fuel tanker must be earthed before fuel is pumped, and describe how earthing prevents a dangerous spark.
