"An Entertainment for Angels tells the story of how electricity charged the eighteenth-century imagination. With contemporary illustrations and engaging prose, Patricia Fara portrays the struggles to understand the unusual and exciting effects that electrical experiments were producing." "One of the heroes of the story is Benjamin Franklin, renowned on both sides of the Atlantic as an expert on electricity, who introduced lightning rods to protect...

Introduction to the essentials of electricity and electronics, includes information on circuits, transformers, semiconductors, transistors, wireless technology, computers, and the Internet, and features quizzes at the end of each chapter and a final exam.

This program explores basic electricity as it was perceived by Benjamin Franklin and other early theorists, as well as the principles of positive and negative charge, conduction and induction, atoms and electrons, and elementary charge. Coulomb's Law is related in detail, including the torsion balance experiment that led to the breakthrough. Insulators, semiconductors, and superconductors are also explained and demonstrated. Specific modules include...

This book is about how electricity has profoundly changed the way we live, work, and play. Some twenty topics are covered, with an abundance of graphs and images to build a comprehensive picture. Each looks at the developments, and the people who initiated them, together with how one led to the next and their subsequent impact on society. Topics include electric supply, lighting through X-rays, and all those appliances that make our homes so comfortable....

Showing how interactions between magnetic fields lead to the production of motion, this program introduces viewers to the inner workings of DC motors. Topics include the work of Hans Christian Oersted, the creation of the first electric motor by Michael Faraday, and the rules for predicting field direction and forces on current carriers. The construction of a simple DC electric motor is shown with helpful graphics and 3-D animation sequences explaining...

What are electromagnetic waves and how was it discovered that light is made of them? How were all the electromagnetic waves (like radio waves) that we can't even see discovered? And how do these electromagnetic waves affect our lives? In this exceptional program, science teacher Spiro Liacos introduces students to waves in general, and then takes a detailed and entertaining look at radio waves, microwaves, infrared light, visible light, ultraviolet...

This program investigates the application and limitations of Ohm's Law. Series circuits and parallel circuits are described. Using equivalent resistance, practical exercises are developed in the application of Ohm's Law to series circuits, parallel circuits, and circuits of greater complexity. Specific modules include Ohm's Law, Series Circuits, Series Calculations, Parallel Circuits, Parallel Calculations, and Complex Circuits. Correlates to all...

This program traces the relationship between magnetism and electricity from the first accidental discovery of induced current. The concepts of electric and magnetic fields are introduced and their representation explored. The features of coils and solenoids are examined to develop the construction of practical electromechanical devices such as solenoid switches and electromagnets. Hand rules are introduced to help determine the alignment of currents...
