Appliance Science
The EU has recently imposed limits on the power ratings of vacuum cleaners, and proposes further limits on appliances such as hairdryers. In this activity students consider a further (fictional) future restriction, on home electricity use. Students calculate the energy transferred in kilowatt-hours by the appliances they use. They then decide how to cut their electricity consumption so as to meet strict new legal limits.
