PowerPoint that covers power and the cost of electricity for a KS3 level class. The starter revisits efficiency and energy stores from previous lessons to enhance memory recall. The power equation (power = energy transferred / time) is covered with an example of how to show working out. Slides include rearranging the equation and unit conversions. The cost equation (cost = power x time x cost per kWh) is also covered. Answers are included.
