The importance of measurements is well known in the field of engineering. This book has been designed as a basic text for the undergraduate students of electrical engineering. It meets the requirements of the syllabus of JNTU and other Universities in India. The primary objective of this book is to present the concepts of electrical measurements in a clear and interesting manner in order to allow an average student to understand the subject independently. The extract and clear representation of various diagrams of measuring instruments is a distinguished feature of this book. With all these features, this book would be extremely useful not only for the undergraduate engineering students, but also for AMIE and GATE candidates.
