Efficiency - GCSE Physics

Efficiency is the ratio of the increase in the useful energy store (output) to the energy in the original store (input). This can either be expressed as a number between 0 an 1, or as a percentage. The efficiency equation is as follows: Efficiency = increase in the useful energy store/energy in the original store or Efficiency = output/input Thanks for watching, Lewis This video is relevant for GCSE Physics 9-1 in the following exam boards: AQA (including Trilogy) Edexcel CCEA OCR A OCR B WJEC CIE (Cambridge International Examinations) IGCSE Edexcel International IGCSE _____________________________________ MY PHYSICS WEBSITES Find even more videos organised by exam board and topic at: GCSE Physics Online ► https://www.gcsephysicsonline.com A Level Physics Online ► https://www.alevelphysicsonline.com MY YOUTUBE CHANNEL Your support in watching this video has been invaluable!
