# Engineering Circuit Analysis 8th Edition by William Hart Hayt

The textbook written by William Hart Hayt, The Engineering Circuit Analysis Eighth Edition (8Th), is mainly focused on students learning themselves. The book used a clear tone and explain each term as it is introduced. Basic concepts are introduced first then explained and Clearfield with examples and practice problems in each chapter. Practice problems are included in each chapter whereas more difficult practice problems are included in the exercise section only. The answers to the selected odd-numbered exercise problems are given.

## Use of Symbols:

The Engineering Circuit Analysis book uses symbolic representation and color printing for a good learning experience. For example, it uses symbols for key point highlighting, a warning for common mistakes, a design problem where multiple answers exist, and problems where computer software is utilized.

## Use of Software:

The computer-based software like PSpice and Matlab is used while solving circuit analysis problems. Keep in mind that it will accelerate the process of solving problems and verifying the answers. A specific symbol identifies the computer-aided problem.

## Engineering Circuit Analysis, Book Organization:

The author William Hart Hayt, first of all, introduces the basic technique of circuit analysis. Starting with Ohm’s Law, Kirchhoff’s voltage and current laws, and Nodal and Mesh analysis. Then circuit simplification techniques are explained, like, source transformation, star-delta transformation, maximum power transfer theorem, and Thevenin and Norton Theorem. Secondly, the author Hayt starts with an Operational Amplifier with simple circuits like comparators and instrumentation amplifiers.

Thirdly, he talks about capacitors and inductors, and their time-response to the Resistor-Capacitor (RC) and Resistor-Inductor (RL) network. Then he grows his discussion on Resistor-Indicator-Capacitor (RLC) and RLC series and parallel networks and their transient response.

Fourthly, the concept of Alternating current is emphasized, starting with force and natural response, phasors, superposition, and source transformation in AC explained. Then the power perspective of the AC circuit is discussed, introducing actual, apparent, and reactive powers.

Fifthly, the polyphase system is discussed starting with different connection types, power measurement in a polyphase system, and the uses of a transformer in AC circuits.

Finally, Laplace transformation, s-Domain, poles, and zeros, transfer-function comes up. The Engineering Circuit analysis book explains the Nodal and Mesh analysis in s-Domain. The concept is followed by frequency response and Bode plot. The Fourier transformation closes the book.
