About the Book: Basic Electrical Engineering has been written as a core course for all engineering students viz. electronics and communication engineering, computer engineering, civil engineering, mechanical engineering etc. Since this course will normally be offered at the first year level of engineering, the author has made modest effort to give in a concise form, various features of Basic Electrical Engineering using simple language and through solved examples, avoiding the rigorous of mathematics. The salient features of this edition D.C. Circuits along with Ohms law and Kirchhoff's laws explained. Faradays laws of electromagnetic induction, Lenz's law, Hysteresis losses and eddy current losses have been discussed. Steady state analysis of a.c. circuits explained. Network theorems explained using typical examples. Analysis of 3-phase circuits and measurement of power in these circuits explained. Measuring instruments like ammeter, voltmeter, wattmeter and energy meter described. Various electrical machines viz. transformers, d.c. machines, single phase and three phase induction motors, synchronous, machines, servomotors have been described. A brief view of power system including conventional and non-conventional sources of electric energy is given. Domestic wiring has been discussed. Numerous solved examples and practice problems for thorough grasp of the subject presented. A large number of multiple choice questions with answer given. Contents: D.C. Circuits Electromagnetic Induction A.C. Circuits Network Theory Three Phase Supply Basic Instruments Transformer D.C. Machines Three-Phase Synchronous Machines Three-Phase Induction Motors Single Phase Induction Motors Power System Domestic Wiring

Engineering mechanics is the branch of the physical science which describes the response of bodies or systems of bodies to external behaviour of a body, in either a beginning state of rest or of motion, subjected to the action of forces. It bridges the gap between physical theory and its application to technology. It is used in many fields of engineering, especially mechanical engineering and civil engineering. Much of engineering mechanics is based on Sir Issac Newton’s laws of motion. Within the practical sciences, engineering mechanics is useful in formulating new ideas and theories, discovering and interpreting phenomena and developing experimental and computational tools. Engineering mechanics is the application of applied mechanics to solve problems involving common engineering elements. The goal of this engineering mechanics course is to expose students to problems in mechanics as applied to plausibly real-world scenarios. Problems of particular types are explored in detail in the hopes that students will gain an inductive understanding of the underlying principles at work; students should then be able to recognize problems of this sort in real-world situations and respond accordingly. Our hope is that this book, through its careful explanations of concepts, practical examples and figures bridges the gap between knowledge and proper application of that knowledge.
