Worksheet questions on calculating efficiency of an appliance. Questions are graded and increase in difficulty (no rearranging/converting, converting units, rearranging equations and converting units, 2-step processes). An answer sheet is included for self-marking/correction.

Used with mid-ability Y10 for P2 - Sustainable Energy on OCR 21st Century, but works with most specifications. Some questions at the end combine the power equation with the efficiency equation.
