How Does Electricity Work

Presents information about electricity and how it is generated and transmitted, including its history; the science behind it; how circuits, power plants, and electrical lines work; and related environmental questions.

Have you ever wondered how electricity powers your home or school? What about how that electricity travels? In any device that uses electricity, inside is a small path called a circuit through which electricity travels. Whether we see them in these devices or not, circuits are constantly at work. But how do circuits work? How were they invented? Explore the key concepts that make up a circuit, including the power source, conducting path, and load. Learn how circuits power devices of all sizes, from computers to the lights in your home to satellites in outer space!

From the duo behind the massively successful and award-winning podcast Stuff You Should Know comes an unexpected look at things you thought you knew. Josh Clark and Chuck Bryant started the podcast Stuff You Should Know back in 2008 because they were curious—curious about the world around them, curious about what they might have missed in their formal educations, and curious to dig deeper on stuff they thought they understood. As it turns out, they aren't the only curious ones. They've since amassed a rabid fan base, making Stuff You Should Know one of the most popular podcasts in the world. Armed with their inquisitive natures and a passion for sharing, they uncover the weird, fascinating, delightful, or unexpected elements of a wide variety of topics. The pair have now taken their near-boundless "whys" and "hows" from your earbuds to the pages of a book for the first time—featuring a completely new array of subjects that they’ve long wondered about and wanted to explore. Each chapter is further embellished with snappy visual material to allow for rabbit-hole tangents and digressions—including charts, illustrations, sidebars, and footnotes. Follow along as the two dig into the underlying stories of everything from the origin of Murphy beds, to the history of facial hair, to the psychology of being lost. Have you ever wondered about the world around you, and wished to see the magic in everyday things? Come get curious with Stuff You Should Know. With Josh and Chuck as your guide, there’s something interesting about everything (...except maybe jackhammers).

We can experience electricity in nature in a few ways, including electricity as lightning and as static electricity. Electricity is a type of energy that can build up in one place or move from one place to another. We need electricity to power our homes, businesses, and electronic devices. Without electricity, we'd depend on candles for light and fire for heat. Young readers are introduced to the components of electricity and how we rely on electricity to go about our daily lives. They'll learn about circuits and how electricity moves.

When Thomas Edison began wiring New York City with a direct current electricity distribution system in the 1880s, he gave humankind the magic of electric light, heat, and power; in the process, though, he inadvertently opened a Pandoras Box of unimaginable illness and death. Dirty Electricity tells the story of Dr. Samuel Milham, the scientist who first alerted the world about the frightening link between occupational exposure to electromagnetic fields and human disease. Milham takes readers through his early years and education, following the twisting path that led to his discovery that most of the twentieth century diseases of civilization, including cancer, cardiovascular disease, diabetes, and suicide, are caused by electromagnetic field exposure. In the second edition, he explains how electrical exposure does its damage, and how electricity is causing our current epidemics of asthma, diabetes and obesity. Dr. Milham warns that because of the recent proliferation of radio frequency radiation from cell phones and towers, terrestrial antennas, Wi-Fi and Wi-max systems, broadband internet over power lines, and personal electronic equipment, we may be facing a looming epidemic of morbidity and mortality. In Dirty Electricity, he reveals the steps we must take, personally and as a society, to coexist with this marvelous but dangerous technology.

Explains how electricity is generated and stored, what items use it, and how to conserve it, and includes instructions on making electrical circuits.

Discusses electricity, and examines what it is, where it is made, how it gets to our homes, and how we use it.

The third edition of this book exposes the reader to a wide array of engineering principles and their application to agriculture. It presents an array of more or less independent topics to facilitate daily assessments or quizzes, and aims to enhance the students' problem solving ability. Each chapter contains objectives, worked examples and sample problems are included at the end of each chapter. This book was first published in the late 60's by AVI. It remains relevant for post secondary classes in Agricultural Engineering Technology and Agricultural Mechanics, and secondary agriculture teachers.
