Fields: Electric Field
Unit 3 Fields: The Electric Field
This Area of Study looks at three fields: Gravitational, Electric and Magnetic. Resources for the other fields are available at Gravitational Field and Magnetic Field.

This Physics Classroom Teacher Tool kit features background readings, interactive simulations with worksheets, Videos and animations, educational research on students' understanding, practical activities including experiments and demonstrations, interactive question modules, problem solving exercises, common misconceptions as well as other links.
This Physics Classroom Teacher Tool kit has the same categories as the Tool Kit for Electric Fields above, but the content is specific to Coulomb's Law.
An article in Physical Review Physics Education Research by Ying Cao and Bárbara M. Brizuela, published in July 2016.
'Teaching Advanced Physics' is a UK resource for teachers new to teaching physics. It assumes only a limited access to equipment, resources, and advice from experienced colleagues. The section on Fields covers Gravitational and Electrical Fields and Electromagnetism. It consists of 16 episodes, each of which is for one or two 60 min lessons. Content of each episode is a lesson plan with a description of the content covered, with points to emphasise in discussion, along with activity or question sheets for the students.
It is recommended that teachers should view any video before purchase.
- Marcom Projects: Static Electricity and Electric Charge, Electric Motors & Electric Generators
Possible practical activities include:
- Practical Physics by Gardiner & White: i) Equipotentials and Electric Fields, ii) Electric Fields and Pot'l Diff in Wires
- PSSC Lab Guide: i) Force between two charged spheres, ii) The addition of Electric forces
- Physics Experiments by McKittrick: i) Charge on a rubbed balloon, ii) Electric fields in circuits
This Institute of Physics (UK) website on practical physics covers the whole of physics. This particular webpage on Electric Circuits and Fields has six practical activities on charges, four on electric fields and four on the Van de Graff generator. Each has a list of equipment, health & safety and technical notes, procedure and teaching notes and articles on related matters. There does not seem to be a download option, but they are easy to copy and paste.
Three experiments: i) Coulomb's Law, ii) Electric field and Potential with teledeltos paper, iii) Electric Field and Potential in a straight wire. Prepared by Dan O'Keeffe, Vicphysics Teachers' Network.
A class experiment to measure the value of the exponent of r in Coulomb's Law and the quantity of charge on a charged rod. The experiment uses a top loading balance, a laboratory jack and a charged rod. Prepared by Vicphysics Teachers' Network.
Templates for Coulomb's Law expt (quick and simple). Includes i)the basic experiment, ii) the decay of the charge on the rod and iii) advanced experiment using the adjusted readings using the half life. Prepared by Vicphysics Teachers' Network.
At the 2020 Physics Teachers' Conference, Dr Barbara McKinnon from Kew High School presented a workshop titled 'D7 Practical Activities for Teaching U3 AOS 1 Fields'. Dr McKinnon provided several documents, these are listed below.
30 Questions from Physics exams in the 1970's. Answers included. Compiled by Colin Hopkins, Bialik College.

This applet is by Paul Falstad. It demonstrates static electric fields and steady currents in 2D for a range of configurations from a single charge to dipoles, quadrapoles, as well as planes. The mouse can be used for a range of movements.
This applet allows the user to set up a distribution of charges, upon which the applet will show the electric potential, electric field lines, and equipotential lines. In addition, the electric force will be observed through real time interaction of charges.
Applet shows electric field lines due to charges. Initially the two charges are equal and equal number of lines of force are drawn from them. The ratio of charges can be varied by increasing the charge on the right.
