Electric fields – CIE AS Level Physics 9702

Contents:-

  • Concept of an electric field
    1. understand the concept of an electric field as an example of a field of force and define electric field strength as force per unit positive charge acting on a stationary point charge
    2. represent an electric field by means of field lines
  • Uniform electric fields
    1. recall and use \(E = \frac{\Delta V}{\Delta d}\) to calculate the field strength of the uniform field between charged parallel plates in terms of potential difference and separation
    2. calculate the forces on charges in uniform electric fields
    3. describe the effect of a uniform electric field on the motion of charged particles
