The branch of engineering which deals with the study, design and application of devices that work on the principles of electricity, electronics and electromagnetism is called electrical engineering. This discipline can be further divided into various sub-fields such as radio frequency engineering, power engineering, instrumentation and control engineering, telecommunications engineering and electronics engineering. It finds extensive application in the field of communication systems, radar and navigation systems, power generation and distribution, etc. A wide range of equipment and tools are used in modern day electrical engineering like oscilloscope, multi-meter, network analyzers and spectrum analyzers. This book attempts to understand the multiple branches that fall under the discipline of electrical engineering and how such concepts have practical applications. The topics included herein on electrical engineering are of utmost significance and bound to provide incredible insights to readers. Those with an interest in this field would find this book helpful.
