Power and Energy - Practice Calculations

This resource contains practice calculations questions for power and energy, ideal for revision or practice, using the equations: P = E/t, P=VI, PI^2R, and E = QV.

• ’Stage 1-2’ questions require students to calculate the magnitude of power using one of the above equations. Students may need to rearrange the correct equation to calculate the magnitude of different variables.
• ’Stage 3-4’ questions equire students to calculate the magnitude of power and energy using one of the above equations. Students may need to rearrange the correct equation to calculate the magnitude of different variables.
• ’Stage 5’ questions (extension) require students to use values in standard form to calculate the power or energy transfered, or the 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.
