This resource contains practice calculations questions for energy efficiency, ideal for revision or practice, using the equation: efficiency = useful / total input.
- ’Stage 1’ questions require students to calculate the magnitude of efficiency using given information.
- ’Stage 2’ questions require students to rearrange the equation to calculate values for different variables.
- ’Stage 3’ questions (extension) require students to use values in standard form to calculate the efficiency or magnitudes of different variables.
A handwritten answer sheet is provided to show students best practices when approached with a calculation question.
This resource has been designed for the AQA specification, but it may also be suitable for other exam boards with a similar syllabus.
