After two centuries of research and experimentation electricity has revolutionised the way we live and become an indispensable part of scientific progress in the electronic age. This unique volume brings vividly to life our exploration of this energy source. Electricity is a vital part of the living world. Our eyes receive light rays and turn them into tiny electrical signals that pass along our nerves into the brain. The chemicals in batteries create electricity to power things like toys and torches. The invention of electric motors gave birth to a whole range of household appliances from stoves and irons to hairdryers and kettles that have shaped the modern world. Featuring historical scientific apparatus and ground-breaking experiments and inventions Electricity is an intriguing look at how we understand and exploit this fundamental form of energy.
