How Electricity Changed the World [PDF ebook] 

Electricity was not the invention of one individual, but the work of many over generations, from civilizations around the world. This book comprehensively covers the invention of electricity, from the cultures that tried to harness the power of lightning over centuries to Benjamin Franklin’s tests with a kite and a key, the industrialization of the lightbulb by Thomas Edison, and the use of electric power today. Through sidebars, fact boxes, and colorful photographs, this book highlights the key moments, positive and negatives impacts, and technological innovations relating to one of the most revolutionary technologies today.
