ABC OF ELECTRICAL ENGINEERING

1. It covers the subject of Basic Electrical Engineering recently introduced by Indian Technical Universities for Ist year students pursuing B.E./B.Tech. (All branches).
2. Simplicity and clarity of expressions are the two hallmarks of the book. It is easy, interesting to read and well-illustrated with neat and simple diagrams.
3. To facilitate Circuit analysis, Network theorems including Kirchhoff's laws have been given in a very student - friendly treatment.
4. Since magnetic circuit forms an integral part of all electric machines, it has been given extensive coverage.
5. Fundamentals of alternating currents and voltages have been discussed along with series and parallel circuits including the phenomenon of resonance. The complex algebra has been made unbelievably simple and easy to understand.
6. The three-phase system of currents and voltages (the most popular in the world) has been given in a very simple but effective treatment. The two wattmeter method for measuring three-phase power and it has been discussed thoroughly because it is the favourite subject of examiners.
7. The basic construction, working principle and operation of D.C. Machines, three-phase and single-phase induction motors and synchronous generators and motors have been given with wide coverage. The development of electromagnetic torque and power flow diagrams have been treated in depth. The concepts of rotating magnetic field, synchronous speed and slip have been explained with remarkable simplicity.
8. Because of its importance from the examination point of view, all aspects of single-phase transformer have been explained thoroughly. The open-circuit and short-circuit tests have been discussed in full detail because these are the favourite topics of the examiners.
9. Another unique feature of this book is that it presents the subject matter in Question and Answer (Q & A) form. It is meant to help the students in two ways:

(a) To make them familiar with the language and type of questions they are likely to get in their examination papers, and

(b) Also to show them how to write the correct answer — neither too short nor too long.
