Moving charge between two charged spheres
This simulation is made upon request by a colleague teaching JC2 this year. The motion of a mobile charge between two source charges is governed by Coulomb’s law ($F =...

Electrostatic Precipitator Simulation
Interact with the simulation of an electrostatic precipitator (ESP) above. The ESP is a big air cleaner for factories and power plants. It uses electricity to pull tiny dust and...
Charging Two Conductors by Induction Simulation
Following a previous simulation on charging by induction , this simulation allows students to investigate the effects of performing the actions of bringing or removing a charged...
Charging by Induction Simulation
In the topic of Static Electricity, charging by induction often presents a challenge for students. The process involves several invisible steps — the movement of electrons, the...
Charge! [Infographics using Canva]
I like Canva for its ease of use and beautiful templates for creating simple infographics. This is an example of one that I did to simplify the content for IP4 Static Electricity.
How to survive a lightning strike
This is an interesting question on electricity: in order to survive a lightning strike, which of the following costumes offer the best protection? A coat of armour, your birthday...
Ionisation of Air to Remove Static Electric Charges
Materials Wool PVC pipe or plastic comb String Lighter Procedure Hang the string from an elevated position. Leave the bottom end free. Rub the PVC pipe with wool. This deposits...
Water Bender
A thin stream of water can be easily bent using a plastic comb or ruler which was previously rubbed with wool. This demonstrates the attractive forces between unlike charges....
Electroscope
An electroscope is a device that can be used to detect or measure the amount of charge in its vicinity. One of the earliest electroscopes is the gold-leaf electroscope which was...
