"Electricity is a form of energy. Electricity is the flow of electrons. All matter is made up of atoms, and an atom has a center, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons. The nucleus of an atom is surrounded by negatively charged particles called electrons.Before electricity generation began slightly over 100 years ago, houses were lit with kerosene lamps, food was cooled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves. Beginning with Benjamin Franklins experiment with a kite one stormy night in Philadelphia, the principles of electricity gradually became understood. In the mid-1800s, everyones life changed with the inventionof the electric light bulb. Prior to 1879, electricity had been used in arc lights for outdoor lighting. The lightbulbs invention used electricity to bring indoor lighting to our homes.Magnetism is a property of materials that respond at an atomic or subatomic level to an applied magnetic field. For example, the most well known form of magnetism is ferromagnetism such that some ferromagnetic materials produce their own persistent magnetic field. Also Electromagnetism has continued to develop into the 21st century, being incorporated into the more fundamental theories of gauge theory, quantum electrodynamics, electroweak theory, and finally the standard model.This book telling this scientific story basicly from ancient Egypt, Greek, Indian and China civilizations to the todays new great inventions such as Maxwells Electromagnetics and Einsteins Relativity theories with modern applications.."

In "On Faradays Lines of Force," James Clerk Maxwell presents a groundbreaking exploration of the nature of electromagnetic fields, encapsulating the scientific dialogue of the 19th century between physics and mathematics. The book employs a meticulous literary style, emphasizing clarity and rigor while employing visual metaphors to elucidate complex concepts. Within this text, Maxwell seeks to expand upon Michael Faradays pioneering work, synthesizing his concepts of field theory and introducing mathematical formulations that laid the groundwork for modern electromagnetism. James Clerk Maxwell, a prominent Scottish physicist, was profoundly influenced by Faradays intuitive approaches to electricity and magnetism. His academic background and teachings at the University of Cambridge substantially shaped his analytical thinking. Maxwells desire to bridge the gap between theoretical mathematics and experimental physics inspired him to elucidate Faradays ideas, developing a coherent framework that validated Faradays experimental insights with mathematical precision. Highly recommended for scholars and enthusiasts alike, "On Faradays Lines of Force" serves as both a historical document and a foundational text in the field of electromagnetism. Readers will gain invaluable insight not only into the science of the era but also into the minds that shaped our understanding of the forces that govern the universe.

Esta obra presenta una perspectiva crítica del análisis, modelado y simulación de sistemas eléctricos en régimen no sinusoidal. En principio, el lector encontrará los fundamentos necesarios para introducirse en los conceptos de calidad de la potencia electrica, en terminos de señales de tension y corriente. En segunda instancia, se vera sumergido en el modelado y la simulacion de sistemas electricos en regimen no sinusoidal, mediante diversas representaciones matematicas, tecnicas de modelado y metodologias de implementacion algoritmica. Por ultimo, se enfrentara a una formulacion diferente, propuesta por los autores, del concepto de potencia en regimen no sinusoidal. Todo esto, basado en un novedoso formalismo matematico, denominado teoria tensorial de la potencia electrica, y sus aplicaciones al estudio de la calidad de la energia. Con la formulacion tensorial de los fenomenos electricos en terminos de los conceptos de potencia es posible analizar, medir, evaluar y compensar de forma integral el deterioro de la calidad de la potencia electrica.

In "Electricity and Magnetism," Elisha Gray presents a comprehensive exploration of the fundamental principles governing these two intertwined forces of nature. The book delves into the scientific laws and phenomena related to electricity and magnetism, employing a didactic style that merges rigorous analytical discourse with practical applications. Grays work is situated within the context of the late 19th-century scientific revolution, a time when the understanding of electromagnetism was rapidly evolving and influencing the burgeoning field of electrical engineering. Elisha Gray, a contemporary of Thomas Edison and Alexander Graham Bell, was an influential inventor and a pioneer in the realm of electrical communication. Grays background in both academia and practical invention, coupled with his fervent curiosity, motivated him to contribute extensively to the understanding of electrical concepts. His innovations, particularly in telegraphy, have cemented his legacy as a key figure in the advancement of electrical technology, ultimately leading him to pen this significant text on electricity and magnetism. I highly recommend "Electricity and Magnetism" to anyone interested in the foundational principles of electrical science and engineering. Whether you are a student, a professional in the field, or simply a curious reader, this book provides invaluable insights into the technological landscape that has shaped modern society. Grays profound knowledge paired with his clear exposition makes this work not only enlightening but also essential for understanding the intricacies of electromagnetism.
