Vladimir Vladimirovich Ryumin became widely known as a popularizer of science and technology. Being a progressive and innovative teacher, he developed his own original teaching methods, carried out unusual experiments, followed news from the world of technology and shared them with his students. Having started teaching, he published many textbooks on chemistry, mineralogy, technology and electrical engineering, a series of brochures on production technology and applied technology... After finishing his teaching career, Vladimir Vladimirovich focused on popularizing science. Today we are pleased to present the book “Entertaining Electrical Engineering at Home.” And although almost a hundred years have passed since it was written, the basics of electrical engineering have not changed since then, the experiments are still relevant and will help to understand the principles of operation of modern electrical appliances, which we use every day without hesitation. The book describes a large number of interesting and useful devices that you can make at home with your own hands. The publication is intended for the widest range of readers.
