4.2.2 Electric Fields

Extended Only

Simple Field Patterns

  • Electric charges create electric fields in the regions surrounding them
    (Similar to the way in which magnets create magnetic fields)
  • The electric field is the region in which another charge will experience a force
  • Fields lines always go away from positive charges and towards negative charges – they have the same direction as the direction of the force on a positively charged particle at a point in that field

 

electric-fields, IGCSE & GCSE Physics revision notesElectric fields are always directed away from positive charges and towards negative charges

 

 

  • Some simple field patterns that you ought to know:

positive-negative-field, IGCSE & GCSE Physics revision notesThe electric field between two opposite charges

 

 

Exam Question: Electric Fields

Author: Jenna

Jenna studied at Cardiff University before training to become a science teacher at the University of Bath specialising in Biology (although she loves teaching all three sciences at GCSE level!). Teaching is her passion, and with 10 years experience teaching across a wide range of specifications – from GCSE and A Level Biology in the UK to IGCSE and IB Biology internationally – she knows what is required to pass those Biology exams.
