Most people are surprised when they learn that electricity is everywhere in the things around them. It is part of each leaf and stone. It is in the ground we walk on and in the air we breathe. Scientists know that all the things we touch and use are really swirling clouds of electricity, but it took thousands of years to find this out.
In All About Electricity, Dr. Ira M. Freeman, a distinguished scientist and college professor, explains what electricity is and how it works. Simply and vividly, he shows how an electric current is established, what an electromagnet is, how electromagnets are used in meters and motors, and how electrical power operates the telephone, the wireless, the radio and television.
Seventy-five diagrams and illustrations by Evelyn Urbanowich add exact details by which the reader can see for himself how one wave differs from another and how each one plays a part in those electrical wonders that have become a part of our everyday living.
