The dual of Thevenin’s theorem. It simplifies a complex linear network down to a single independent current source ( Incap I sub n ) in parallel with a single resistor ( Rncap R sub n
His career culminated at , where he mentored doctoral students and shaped the next generation of engineers. Notably, his academic lineage includes one documented student who went on to have over 1,000 academic descendants, highlighting his indirect influence on the field. This combination of practical experience and theoretical expertise is reflected in the thorough, application-driven nature of his textbook.
Cassell’s approach hinges on the . This is the golden rule of linear systems—that in a circuit containing multiple independent sources, the voltage or current response in any branch is the algebraic sum of the responses caused by each source acting alone.
): The voltage is proportional to the time rate of change of the current ( Capacitors (

An electric circuit is considered linear if it satisfies the principle of , which comprises two core properties: homogeneity (scaling) and additivity .
Linear electric circuits by Wallace L. Cassell - Open Library The dual of Thevenin’s theorem
States that any combination of linear voltage sources and resistors can be replaced by a single equivalent voltage source ( Vthcap V sub t h end-sub ) in series with a single resistor ( Rthcap R sub t h end-sub
Grid analysis and power factor correction rely entirely on linear AC circuit math (impedance and admittance).
If you’re a student or instructor, here’s what you can do:

Given the book's clear value, why does a free PDF seem so difficult to find? The primary reason is . As a work published in 1964 by a major publisher, its copyright is still active. For a book to be in the public domain in the United States, it typically must have been published before 1928. Since this book is from 1964, its copyright is still in effect. Therefore, hosting or distributing a full PDF without permission from the rights holder (likely John Wiley & Sons) would be a clear copyright infringement. This legal barrier is the single biggest reason a "free" PDF is not easily accessible on official sites like the Internet Archive.
It offers an in-depth approach that is often lost in modern, condensed textbooks.
Diodes, transistors, and vacuum tubes do not follow a straight-line relationship. A small change in voltage can result in an exponential change in current. 2. Core Concepts Covered in Linear Circuit Textbooks
This widespread adoption speaks to the book's clarity, rigor, and pedagogical strength. The systematic, building-block approach—from physical models, to Laplace and Fourier analysis, to network topology and filter design—remains a timeless and effective method for teaching this material. For students and professionals who work with analog circuits, signal processing, or power systems, this text provides a rock-solid foundation.
