Geogebra App on Maximum Power Theorem

 GeoGebra link: 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

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. Thereafter, as some students remained confused, I merely reverted to explaining the rules. Eventually, I resorted to simplifying the equation by substituting simple numerical
