PREFACE TO THE FIRST EDITION BY C. L. Wadhwa:
Electrical Engineering has been written as a core course for all engineering students viz. Electronics and Communication, Computer Engineering, Civil, Mechanical Engineering etc. With advancement in technologies in almost all spheres of engineering, it is becoming difficult to provide more than one slot for interdisciplinary courses. However, the author feels that no engineering can work without electric energy. The basic input to all engineering is the electric energy. A basic course on Electrical Engineering is almost essential for all engineering students. Keeping this compulsion in mind and also that this course will normally he offered at the first year level of engineering, the author has made modest effort to give in a concise form various features of Electrical Engineering starting from simple ac circuits to Network theorems, measuring instruments, transformers, various de and ac machines including stepper motor. Various physical phenomenon have been explained using simple language avoiding the rigorus of mathematics.

Basic Electrical Engineerin 4th Edition By C. L. Wadhwa

Chapter I deals with the steady state analysis of a.c. series and parallel circuits and series and parallel resonance.

Chapter II describes various network theorems, star-delta transformation and methods of mesh and nodal analysis for de networks.

Balanced and unbalanced, three phase circuits have been analysed and methods of 3-phase power measurements have been discussed in Chapter III.

Measuring instruments like, ammeter, voltmeter, wattmeter and energy meter have been described in chapter IV.

Transformer is a very important electrical equipment. The construction, principle of operation, parameter calculations, efficiency and regulation of transformer have been discussed in chapter V.

Chapter VI deals in types of de machines, their operation and characteristics, efficiency and speed control and application of these machines.

Chapter VII deals into the construction, principle of operation and applications of three phase synchronous motors and stepper motor. 

Three phase induction motors form atmost 60 to 70% of the total load on power system. These motors have been discussed in chapter VIII including types, construction, principle of operation, methods of starting, torque-slip characteristic, application and single phasing operation. Single phase induction motors find wide application in Office and domestic appliances. Construction, principle of operation and application of these motors have been described in chapter IX.

Power systems is the most capital intensive and the most complex system ever developed by man. Chapter X gives in brief, various supply and distribution systems and suggests methods for improvement of power factor.

A large number of problems have been solved to help understand the theory. At the end of each chapter unsolved problems with their answers have been suggested for further practice. At the end, a large number of objective type questions have been added to help the reader to test himself.

Any constructive suggestion for the improvement of the book will be gratefully acknowledged.

Last but not the least, I with to express my gratitude to my wife Usha, daughter Meenu and son Sandeep for their patience and encouragement during the preparation of the book.
