This book deals exhaustively with electrical and electronic circuit processes. Most textbooks neither describe accurately nor precisely the mechanism of the processes in the operation of electrical and electronic circuits. Common misconceptions that are dispelledin the book.The contents provide an accurate and correct viewpoint of these very fundamental electric and magnetic processes. Every case has been dealt so that a present-day electrical and electronic engineer understands these physical and applied aspects at the first levelbefore he/she studies topics of electromagnetic field theory and electrical circuits or networks. Electrostatics and electric circuits belong to one science and the contents of the book are vital to bridge the gap that present curricula have created between them. Basedon latest research findings that unify the two concepts, using vivid diagrams depicting circuit processes with states evolving in time, the student is guided smoothly through the topics on the mechanism of conduction, operation of capacitive and inductive circuitssubject to steady and alternating voltages; operation of motors, generators, microphones and loudspeakers and p-n junctions.The revised (2013) edition includes a section describing the function, fabrication and operation of non-rectifying contacts in the chapter on p-n junctions along with animated power point slides depicting their operation in the accompanying CD.The chapters combine text with several illustrative figures and derivations of formulae. The animated power point slides (included in the accompanying CD) for all chapters cover every pertinent principle that will aid readers in visualizing circuit processes. TheCD accompanying the revised (2013) edition includes results of simulation runs of circuits that superimpose ac signals on dc voltages and of CR phase-shifting networks typically used in RC Phase shift oscillators. Procedures to obtain these using TINAsimulation software are also provided in the CD.The contents of the chapters are aimed to develop a strong sense of feel of the mechanism of electric and electromagnetic phenomenon, the important role of electric fields in circuit processes and the transport of energy in circuits. They enhance analytical ability and reasoning skills in solving electric and electronic circuit problems. With critical inputs and encouragement from renowned Professors Hermann Haertel, Bruce A. Sherwood, David J. Griffiths, Norris W. Preyer, Satyabrata Jit and Dipankar and several other experts in this important field, the book is strongly recommended for basic electrical and electronics courses as a text to give students a conceptual and physical basis of electric and magnetic fields.
Sridhar Chitta :- :Associate Professor, Electronics and Communication Engineering, Matrusri Engineering College, Hyderabad, obtained B.E. in Electronics and Communication Engineering from Regional Engineering College (now NIT), Tiruchirapalli (Madras University) in 1976 and M.E. in Control Systems from Victoria Jubilee Technical Institute (Bombay University) in 1980. His current research interests are in the area of Large Scale Control Systems. He has over 20 years of experience as a practicing engineer in industry in India, the Middle East and Canada. As an active life member of I.S.T.E, he has delivered scintillating lectures on unified Electric theory and Circuit Process Mechanisms using animated power point presentations to various engineering college faculty members and students.
