Preface to Basic Electrical Engineering


This e-book is primarily supposed for a course in Basic Electrical Engineering. A robust want was felt for such a e-book, which might deal with the wants of Indian College students hailing from totally different backgrounds throughout the nation.

The e-book is written in two elements. Half A covers the essential matters of circuit evaluation and primary instrumentation. Half B offers with the ideas of Electrical Machines. Half A has six chapters.

Chapter 1 of Half A, introduces the coed to the 2 elementary legal guidelines of Electrical Engineering which kind the premise for all different matters, specifically Ohm’s legislation and Kirchhoff’s legal guidelines.

Chapter 2 offers with the basic ideas in Electromagnetism—definitions of elementary portions, Biot-Savart’s legislation, Faraday’s legal guidelines, Self Inductance, and Mutual Inductance.

Chapter 3 covers the varied strategies of circuit evaluation—nodal evaluation, mesh evaluation, superposition theorem, Thevenin’s theorem, Norton’s theorem, most energy switch theorem, reciprocity theorem, star-delta transformation—utilized to easy dc circuits.

Chapter 4 introduces the scholars to the basics of ac circuits. The answer of straightforward collection and parallel ac circuits is introduced.

Chapter 5 presents the ideas of three-phase circuits. The answer of balanced three-phase star and delta related networks is handled on this chapter. The chapter additionally discusses the varied strategies for the measurement of three-phase energy.

Chapter 6 exposes the coed to widespread electrical home equipment and electrical engineering practices we come throughout in everyday life.

The chapter covers the matters of strategies {of electrical} wiring, selection of cables, easy wiring schemes, working precept of fuses, the precept of MCBs, earthing strategies, widespread lighting sources, estimation of power requirement for easy hundreds, causes and prevention of electrical shocks.

Lastly, chapter 7 covers the fundamental ideas {of electrical} measurement. Shifting coil and shifting iron devices, dynamometer wattmeter, and power meter are mentioned intimately. Half B is dedicated to the remedy of Electrical Machines.

Chapter1 presents the basic ideas of electrical machines.

Chapter 2 offers with turbines. The development, precept of operation and derivation of induced emf are introduced intimately.

Chapter 3 offers with the operation, sorts, and traits of dc motors. It additionally covers the essential matters of testing and velocity management of dc motors.

Chapter 4 is dedicated to transformers. The constructional options, operation, phasor diagram, testing, computation of effectivity and regulation are mentioned intimately.

Chapter 5 offers with three-phase induction motors, that are probably the most rugged and broadly used within the business.

Chapter 6 presents the three-phase alternators. The development, emf equation and totally different strategies of regulation are lined intimately.

Chapter 7 covers single-phase induction motors.

Chapter 8 provides the experimental process for a few of the widespread experiments performed within the electrical machines laboratory.

All chapters are introduced in a easy and lucid method to facilitate a straightforward understanding of the topic. Vital ideas are highlighted to emphasise the necessity to bear in mind them.

Each chapter incorporates plenty of solved examples to strengthen the training of the coed and assist the coed, apply the ideas in varied contexts.

The examples introduced assist the scholars to narrate summary ideas in Electrical Engineering to sensible purposes that they see of their day by day lives. Each chapter additionally provides plenty of questions and unsolved issues for the coed to work out.

The e-book can be utilized as a textbook for a course in Basic Electrical Engineering, a elementary course in Electrical circuits and additionally for a primary course in Electrical Machines.
