Preface to circuit Analysis PDF
The field of electrical and electronic engineering is vast and diverse. However, two topics hold the key to the whole field. they’re ‘Circuit Theory’ and ‘Signals and Systems’. Both these topics provide a solid foundation for later learning, also as for future professional activities.
This undergraduate textbook, the primary of a two-book series, deals with one among these two pivotal subjects intimately .
In addition, it connects ‘Circuit Theory’ and ‘Signals and Systems’, thereby preparing the student-reader for an in depth study of this important subject either concurrently or subsequently.
The theory of electrical circuits and networks, a topic derived from the more basic subject of electromagnetic fields, is that the cornerstone of electrical and electronics engineering.
Students got to master this subject and assimilate its basic concepts so as to become competent engineers.
my book Electric Circuits and Networks (ISBN 978-81-317-1390-7), published by Pearson Education in 2009, was an effort to supply a solid foundation on electric circuits and networks to the undergraduate students.
However, this book was perceived as being too voluminous and too comprehensive for the first-level course on Circuits. Hence, for better acceptability and better utilization of the content, i made a decision to rewrite the fabric and present it in two books.
Of these, the primary one on circuit Analysis has been designed to function a textbook for first/second-level courses on circuits and therefore the other on Electric Network Analysis and Synthesis has been envisaged for a complicated level course on network analysis and synthesis.
The latter text is being augmented with additional content that caters to the requirements of the advanced user.
This text, circuit Analysis, is that the first of the series, while work on the second text with new material included on network functions, electric filters, and passive network design, is currently ongoing .
Objectives of the Book Series
Primary Objective: To function textbooks which will meet students’ and instructors’ need for a one/ two-semester course on electrical circuits and networks for undergraduate students of electrical and electronics engineering (EE), electronics and communications engineering (EC) and allied streams.
This textbook series introduces, explains, and reinforces the essential concepts of study of dynamic circuits in time-domain and frequency-domain.
Secondary Objective: To use circuit theory as a carrier of the basics of the linear system and continuous signal analysis in order that the scholars of EE and EC streams are well-prepared to require up an in depth study of higher-level subjects like analog and digital electronics
Pulse Electronics, analog, and data communication systems, digital signal processing, control systems, and power electronics at a later stage.
Electric Circuits in EE and EC Curricula
The subject of electrical Circuits and Networks is currently covered in two courses in Indian technical universities.
The introductory portion is roofed as a neighborhood of a course offered within the first year of the undergraduate program. it’s usually called ‘Basic Electrical Engineering’.
About half the course time is dedicated to introductory circuit theory covering the essential principles, DC circuit analysis, circuit theorems, and single-frequency sinusoidal steady-state analysis using phasor theory. This course is typically a core course for all disciplines.
Therefore, it’s limited considerably in its content and depth as far as topics in circuit theory are concerned. The course is aimed toward giving an summary of EE to undergraduate students of all engineering disciplines.
Students of disciplines aside from EE and EC got to tend a quick exposure to electrical machines, industrial electronics, power systems, etc., within the third semester. many universities include this content within the sort of a course called ‘Electrical Technology’ within the third semester for college kids of other engineering disciplines.
This approach makes it necessary to show them AC steady-state analysis of RLC circuits even before they will be told about the transient response in such circuits.
EE students, however, need AC phasor analysis only from the fourth or fifth semester once they start on Electric Machines and Power Systems. But the first-year course on basic EE has got to be a standard course and hence even EE and EC students learn AC steady-state analysis before the transient response.
The second course on circuits is typically taught within the third or fourth semester and is termed ‘Electric Circuit Theory’ for EE students and ‘Circuits and Networks’ or ‘Network Analysis’ for EC students.
Few comments on these different course titles and course content are so as . Traditionally, undergraduate circuit theory courses for EE stream slant towards a ‘steady-state’ approach to teaching circuit theory.
The syllabi of the many universities in India contain extensive coverage on single-phase and three-phase circuits with the transients in RC and RL circuits postponed to the last module within the syllabus.
The course instructor usually finds himself with insufficient contact hours towards the top of the semester to try to to full justice to the present topic. EE stream often orients Circuits courses to function prerequisites for courses on electrical machines and power systems.
This led to the EC stream preparing a special syllabus for his or her second-level circuit theory course one that was expected to orient the scholar towards the dynamic behavior of circuits in time-domain and analysis of dynamic behavior within the frequency domain.
But, in practice, the syllabus for this subject is an effort to crowd too many topics from Network Analysis and Synthesis into what should are a basic course on Circuits.
Such a difference in orientation between the EE-stream syllabus for circuit theory and EC-stream syllabus for circuit theory is neither needed nor desirable.
The limit between EE and EC has blurred considerably over the previous couple of years. In fact, students of both disciplines need good coverage of Linear analysis or Signals and Systems within the third or fourth semester.
Unfortunately, Linear analysis has gone out of the curriculum even in those universities which were wise enough to introduce it earlier, and Signals and Systems have started making its appearance within the EC curriculum in many universities.
But the EE stream is yet to lose its penchant for AC steady-state in many Indian technical universities. the topic of circuit theory is as electronic because it is electrical . Inductors and capacitors don’t get scared and behave differently once they see a transistor.
Neither do they reach sinusoidal steady-state without browsing a transient state simply because they happen to be a part of an influence system or electrical machine? Against this background, I state the pedagogical viewpoint I even have adopted in scripting this textbook.
