Description max 80 words

A practical guide for young inventors, this book demystifies electricity through clear explanations of units like the ampere and volt, detailed instructions for building wireless telegraph stations, Tesla coils, and custom dynamos, and a passionate appeal to American boys to become self-reliant engineers.

Summary up to 500 words

Published in 1913 by Alfred Powell Morgan, *The Boy Electrician* serves as an educational manual designed to stimulate the inventive faculties of young readers. The text begins by establishing fundamental electrical concepts, explaining that invisible current is measured by its chemical, magnetic, or heating effects. It introduces the standard units: the ampere (current), volt (pressure), and ohm (resistance), illustrating their relationship through Ohm's Law (C = E/R). The book further defines power in watts and distinguishes between direct and alternating currents. The narrative progresses to practical applications, focusing heavily on wireless telegraphy. Morgan explains the theory of electromagnetic waves traveling through an 'ether,' using the analogy of ripples in a pond. Readers are guided step-by-step on constructing their own stations, including erecting aerials (antennas) in various shapes like the 'V' or 'T' type, and building simple transmitters using induction coils and spark gaps. The receiving end is detailed with instructions for creating sensitive detectors using crystals like galena to convert high-frequency alternating currents into audible signals via telephone receivers. A significant portion of the text is dedicated to constructing a Tesla High-Frequency Coil. Morgan provides specific dimensions for winding primary and secondary coils, selecting appropriate insulators like hard rubber, and assembling the device to produce high-frequency sparks. He notes that while the visual effect is striking, the currents are safe enough to hold in one's hand without shock, though they may cause warmth. Throughout the text, Morgan emphasizes the importance of finishing work properly, criticizing the tendency of boys to abandon projects prematurely. The book concludes with a plea for care and ingenuity, encouraging readers to improve upon the designs provided. It asserts that while the book covers many phases of practical electricity, true mastery comes from common sense and personal experimentation when facing unique problems not found in any manual.
