The amount of energy an appliance transfers depends on how long the appliance is switched on for and the of the appliance. Describe the energy changes that are taking in a given electrical appliance – stating which energy transfers are useful and which are wasted. Describe how the amount of energy transferred depends on the time the appliance is on for and the power of the appliance. 0.5 What energy changes take place in electrical appliances? WS 1.4 Explain everyday and technological applications of science.
