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 variable in this app as well). Since the power dissipated by the resistor is given by and the current is given by , This power will be a maximum if the expression for

## 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 divider and the setup can be used to measure emf or potential difference across a variety of circuits components. Basically, students need to understand the rule - that

## Geogebra Apps for Singapore Physics

I've curated a series of Geogebra apps that are relevant and useful for the instructional objectives under the Singapore-Cambridge GCE 'O' and 'A' level syllabi. Some of these apps were created by myself. If you have any ideas for new Geogebra apps, do let me know in the comments section below and I'll see if
