The book provides a working knowledge of the electrical power field. Equations are avoided as far as possible. The electrical power industry is a massive one, which has enabled the current level of human civilization. But it retains its position as among the top polluters of earth. It is therefore imperative that as many people as possible understand it. The current trend is to move out of electrical power into the computer, telecommunication, and robotic space, so this book is one attempt to simplify it such that more will venture into it. It starts with the overall picture of electricity. Then safety concepts are discussed to enable the building of common-sense approach toward it. The history of electricity is the next topic because we need to know how it all started to understand the current system. Then new concepts to fight pollution are elaborated upon, including the electric cars and the decision-making process on which energy source to choose from. It is critical to understand that there is no one-size-fits-all solution and energy source depends on climatic conditions and logistics. The final portion dwells on the future developments in the electricity business. A general term, the Smart Grid describes the ever-growing use of the Internet (TCP/IP) protocol versus the current Ethernet (SCADA) and ever-expanding computer power to control the grid. Then there is the IoT and Digital Twin developed by GE. A caveat is made and explained how all these controls must be taken.
Most of us take the supply of electricity for granted - This booklet gives simple explanation of what is electricity and how it reaches your home. Concepts such as AC and DC current and a few simple electrical components and their functions explained. Mathematical expressions are totally avoided. Drawings and illustrations are provided almost in every page to support the explanations and to make the book readable. This book is recommended foe every one and to be kept at home for easy and casual reading to facilitate understanding of the flow of electricity to your house. Students beginning their graduate courses in Physics and Engineering would also find this book very useful to understand the concepts and to have a strong understanding of Electrical concepts before taking up more advanced subjects on Electricity or Electrical Engineering.
