DeLight Game
How to Play DeLight DeLight is a turn-based circuit-building game for two teams: Red and Blue. Your goal is to connect bulbs into the shared circuit and finish with more total...

AC to DC Rectifier Simulation
This simulation shows how a full-wave bridge rectifier converts alternating current into pulsating direct current. The ideal diodes redirect both halves of the AC waveform so that...
Capacitance Equations
This app is an interactive tool for teaching how capacitors behave when connected in series and parallel . Students can enter values for two or three capacitors and switch between...
Simulation for Series and Parallel Circuit
Circuit Configuration: Series Circuit Parallel Circuit Bulb 1 Resistance (Ω): 2.0 Ω Bulb 2 Resistance (Ω): 2.0 Ω Drag the ammeter (A) or voltmeter (V) onto a bulb to attach....
RC Circuit
This is meant for the A-level topic of Circuits, for which students have to describe and represent the variation with time, of quantities like current, charge and potential...
Internal Resistance and Terminal Potential Difference
https://www.geogebra.org/m/puvfjxk5 This applet demonstrates how terminal potential difference (as measured by the voltmeter across the terminals of the battery) changes depending...
Potential Divider with Thermistor Applet
The wonderful thing about GeoGebra is that you can whip up an applet from scratch within an hour just before your lesson and use it immediately to demonstrate a concept involving...
Geogebra App on Maximum Power Theorem
GeoGebra link: https://www.geogebra.org/m/hscshcj8 This simulation demonstrates the power dissipated in a variable resistor given that the battery has an internal resistance (made...
Geogebra Simulation of a Potentiometer
Some of the more challenging problems in the topic of electricity in the A-level syllabus are those involving a potentiometer. The solution involves the concept of potential...
DeLight Version 2
I modified "DeLight", the board game that I designed a few years back into a worksheet version (for small groups) as well as a powerpoint version (that teacher can facilitate as a...
Concrete to Abstract
As I was teaching the use of the potential divider equation to my IP4 (Grade 10) students last week, I approached it by teaching the rules first before showing worked examples....
Internal Resistance and Maximum Power Theorem
I've created this simulation to demonstrate the effect of an internal resistance due to a cell on the potential difference and current of an external load. One can also vary the...
Variable Resistor Simulation
My third simulation in as many days. This time round, I created some png files for electrical circuit components that can be used for future simulations. I also figured out how to...
Simulation for Potentiometer
Continuing the course on Easy Java Simulation, I did this simple simulation on the Potentiometer, which allows students to first predict, and then verify the position of a jockey...
