The branch of engineering that is concerned with the study and use of electronics, electromagnetism and electricity is known as electrical engineering. It is subdivided into a number of significant subfields, which include power engineering, control engineering, telecommunications, robotics, signal processing, microelectronics, etc. Electrical engineering has been instrumental in the development of various innovative technologies, such as electrical power generation, GPS technology, etc. The lighting and wiring of buildings, the operation of power stations, the electrical control of industrial machinery, the design of telecommunication systems and the design of household appliances are all within the scope of this field. Modern electrical engineering uses computer-aided design for the design of electrical systems. A wide range of instruments and tools are used in electrical engineering, such as multimeters, oscilloscopes, network and spectrum analyzers, etc. This book covers in detail some existing theories and innovative concepts revolving around electrical engineering. There has been rapid progress in this field and its applications are finding their way across multiple industries. Students, researchers, experts and all associated with this field will benefit alike from this book.
