Thevenin and Norton's Theorems: Powerful Pedagogical Tools for Treating Special Cases of Electric Circuits

The importance of Thevenin's and Norton's theorems when dealing with special cases of electric circuits is demonstrated. These cases have typically been dealt with in difficult and non-systematic ways and as a result, pedagogical effectiveness is minimised and students are reluctant to tackle them. These theorems are powerful pedagogical tools for the solution of many problems in circuit analysis.
