This lesson delves into the properties of resistors in circuits, students should complete a practical that looks at the properties of fixed and variable resistors.
Equations will need to be used to calculate resistances. This lesson focusses on students ability to use two required equations to calculate power.
Both equations are explained, standard units are highlighted and derivation of one of the equations is discussed.
Every question should be approached from a 3 mark perspective (1 for substitution into the equation, 1 for the correct answer and 1 for the correct units).
Students should be walked through the practice questions and then given time to carry out some individual questions using an approved AQA worksheet.
This should be backed up with an AQA approved worksheet on this topic.
