Electronics Simplified
Electronics Simplified, Third Edition, discusses the aims and methods of electronics, with emphasis on digital electronics and software options. It covers the latest developments in electronics, including Blu-ray, digital TV and radio, HD and 3D TV, robotic systems, radar, cellular phones, GPS, and microcomputers. Organized into 17 chapters, the book introduces the reader to every aspect of electronics from fundamentals to applications, with minimal mathematics required. It provides an overview of electricity, waves, and pulses and how a steady voltage is generated, along with power, alternating voltage, and AC and DC transmission. The information on microcomputers has been greatly expanded, while information on analog fundamentals has been retained. It also discusses passive components such as transformers, resistors and capacitors, inductors, transformers, resonance, and diodes; active components and integrated circuits, particularly what a transistor is and what it does; how traditional radio works; elements of television, including color television; digital television and radio broadcasting; and digital signals and digital recording. Finally, the principles of CD recording are explained, along with the basics of microprocessors, calculators, computers, and computer peripherals. This book is essential reading for hobbyists, technicians, professionals, and students. It is suitable for anyone taking a qualification course in electronics, or for those who want to know more about the digital revolution. - Explains electronics from fundamentals to applications – No other book has such breadth of coverage - Approachable, clear writing style, with minimal math – No previous knowledge of electronics required! - Now fully revised and updated to include coverage of the latest developments in electronics: Blu-ray, HD, 3-D TV, digital TV and radio, miniature computers, robotic systems and more
Understanding Primary Science
Many primary teachers need help with their personal subject knowledge in science. Now that there is a nationally published scheme of work for science in primary schools, many teachers also need help in constructing lesson plans in order to cover all of the themes and possible activities in the scheme. Designed with those needs in mind, this book provides practical help in the form of sample lesson plans together with linked background subject knowledge for each of the science topics in the primary national curriculum. Each chapter has sample lesson plans for four different age-groups: reception, years 1-2, years 3-4 and years 5-6.
Electricity Pricing
As the advent of the Smart Grid revolutionizes how homeowners and businesses purchase and manage power, electricity pricing is becoming more complicated and intricate than ever before, while the need for more frequent rate revisions remains a primary issue in the field. A timely and accessible guide for the new industry environment, Electricity Pricing: Engineering Principles and Methodologies helps those involved in both the engineering and financial operations of electric power systems to "get the money right" while ensuring reliable electric service at a fair and reasonable cost. Explores both the business functions and engineering principles associated with electricity pricing Examining pricing approaches and opportunities, this book presents tools, viewpoints, and explanations that are generally not found in contemporary literature. It clarifies valuable analysis techniques, realistic examples, and unique lessons passed along from those inside the industry. This "how to do it" guide fosters a multidisciplinary understanding that integrates information, methodologies, and techniques from accounting, economics, engineering, finance, and marketing. Detail-oriented but still mindful of the big picture, this book examines the complex relationship between electricity, customers, and service providers in relation to pricing. Electricity Pricing also: Presents mathematical methods and techniques used to establish electricity prices, determine cost causation, and evaluate pricing structures and mechanisms Explores ways to translate and integrate cost elements into practical pricing structures Details how engineering concepts are used to apportion production, delivery, and associated costs to determine cost of service and to support all aspects of ratemaking strategy, design, analysis, and decision making This comprehensive professional reference addresses theory but remains grounded in no-nonsense practical applications. It is dually suited to introduce newcomers to the technical principles and methodologies of electricity pricing and provide veterans with a valuable consolidation of advanced tools for pricing analysis and problem solving.
