No problem with book and the content in this book is just like short notes for revision.Already who studied those concepts can only understand it clearly. But I am dissatisfied with Amazon as they charged me extra amount. Same book is available at book stores at price lesser than Amazon's price
This book is very good for competitive exam preparation. Mathematics chapter is completely left out in this book. Some topics like protection switchgear, single phase induction motor, some important laws are also missing. If these contents are added this book will fulfill the syllabus.
I won't recommend this book to a beginner as it just contain only formulae. There is no explanation to anything. Highly disappointed with the book. Got this book after reading reviews but not worth any penny. But I'll say that it is good for revision purpose. Other than that it's not a good book. Someone who lacks concept, this book is not for you.
The book is very helpful for quick revision, especially for GATE ,ESE, and other state electricity board. Almost all topics are covered ,the book is revised and updated. Paper quality and printing are worth its price.
It is good for quick revision, every subject is cover into 30 pages ,book is small and it not take much time to revise all the formula and key concepts,but this is only good if you have very much understanding of the subject earlier.
