Electricity (DK Eyewitness Books)
Eyewitness Electricity brings vividly to life our exploration of this powerful natural force. It 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 to the brain. The chemicals in batteries create power for such things as toys and flashlights. The invention of electric motors enabled the creation of a whole range of household appliances that have shaped the modern world. See how electricity works nerves and muscles and what causes lightning. Learn how electricity can transmit voices and images across an ocean and what makes a silicon chip work. Discover the amazing speed of charged atoms, what happens when you tune in the radio, and much, much more!
