A-B-C of Electricity

Aimed at young readers and nontechnical adults, this elementary introduction explains the nature and measurement of electricity—volts, amperes, and ohms—using water and pressure analogies, then surveys magnetism and practical applications such as the telegraph, wireless telegraphy, telephone, electric lighting, power generation, and batteries. Chapters combine clear definitions, illustrations, and step‑by‑step descriptions to show how electricity is produced, transmitted, insulated, and employed in devices and systems, and the volume closes with observations on recent developments and encouragement for further practical study.
