    Chapter 33 Thévenin’s and Norton’s theorems Why it is important to understand: Thévenin’s and Norton’s theorems Two powerful circuit analysis techniques are Thévenin’s theorem and Norton’s theorem. Both theorems convert a complex circuit to a simpler series or parallel equivalent circuit for easier analysis. Analysis involves removing part of the circuit across two terminals to aid calculation, later combining the circuit with the Thévenin or Norton equivalent circuit. Thévenin’s theorem was independently derived in 1853 by the German scientist Hermann von Helmholtz and in 1883 by Léon Charles Thévenin (1857–1926), an electrical engineer with France’s national Postes et Télégraphes telecommunications organization. Norton’s theorem is an extension of Thévenin’s theorem and was introduced in 1926 separately by two people: Hause-Siemens researcher Hans Ferdinand Mayer (1895–1980) and Bell Labs engineer Edward Lawry Norton (1898–1983). This chapter explains both theorems, analysing both d.c. and a.c. networks through calculations. At the end of this chapter you should be able to: • understand and use Thévenin’s theorem to analyse a.c. and d.c. networks • • understand and use Norton’s theorem

    Leon Charles Thevenin was a French telegraph engineer who worked on Ohm's law and extended it to the analysis of complicated electrical networks. He is remembered today almost entirely for one small piece of work. His theorem, published in 1883, was based on his study of Kirchhoff's Laws and is found in every basic textbook on electrical circuits. It has made his name familiar to every student of electrical circuits and to every electrical and electronics engineer. Leon Charles Thevenin was born at Meaux just outside Paris on March 30, 1857. He graduated from the Ecole Poly technique in 1876 and two years later joined the Corps of Telegraph Engineers. The public telegraph service was to be his working life until his retirement in 1914 on the eve of the first World War. During those 36 years he showed himself to be a great engineer, an excellent administrator and, perhaps first and foremost, a teacher. He continued some of his teaching duties to the end of his life. At the start of his career, Thevenin joined the department responsible for long-distance underground telegraph lines which was then vastly expanding its service and requiring most of the newly trained young engineers. But he did not stay there long. His unusual talents were recognized and, he moved to the Departmen
