Electric circuit analysis is an introductory course for all branches of engineering and especially for electrical, communication and instrumentation engineers. In electric circuit analysis, one learns about the basics of electrical circuit elements and how to connect them in circuits. The solution techniques to solve them. During this process, learn several basic mathematical techniques that will be useful to solve ordinary linear differential equations. These equations appear throughout the curriculum of both undergraduate and graduate programs. Hence, there is a need to pay special attention to this circuit analysis. It will pay big dividends in the future-whether or not you are using circuits.The main objective of this edition is to expose basic circuit concepts, circuit models and methods of circuit analysis in time domain and frequency domain for solving simple and multidimensional circuits including coupled circuits and three phase circuits. This book has been completely revised taking into account syllabus of all universities for the following branches of study: Electrical and Electronics Engineering; Electronics and Communication Engineering; Electronics and Instrumentation Engineering; Instrumentation and Control Engineering.Each chapter contains an Introduction, Summary, Review Exercises (Problems with Answers) and Model Question Papers to motivate the students and to make them understand the concepts.This edition is for sale in India, Bangladesh, Bhutan, Maldives, Nepal, Myanmar, Pakistan and Sri Lanka only.
