This is the story of how electrical energy is generated in a power station and how it travels through pylons, power cables and wires until it reaches towns and homes. Children will discover how this electrical current is created and how it is made safe, and how it supplies domestic appliances with the power to work. At the end of the book there is an activity in which children can make a simple electric circuit. This volume is part of a series which uses cartoon-style illustrations and speech bubbles to make scientific ideas easier to understand. Fact boxes, a themed experiment, a list of related Web sites and an index are also included."
