Summary:

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
