SUMMARY

The discussion focuses on three fundamental electrical engineering theorems: Thevenin's Theorem, Norton's Theorem, and the Superposition Principle. Thevenin's Theorem simplifies a complex linear circuit to a single voltage source and series resistance, while Norton's Theorem converts it into a current source and parallel resistance. The Superposition Principle allows for the analysis of circuits with multiple sources by considering the effect of each source independently and summing the results. A practical example illustrates the Superposition Principle using charged particles and their contributions to an electric field.

PREREQUISITES
  • Understanding of linear circuit theory
  • Familiarity with electrical components such as resistors and voltage/current sources

Unfortunately, I am unfamiliar with the first 2 theorems, but I can explain you the superposition one.
Imagine, for instance, you have got a known amount of charged particles in space, and you would like to know the electric field at a specific point in space, you would simply add each force made by each particle on that specific place.
The superposition theorem assumes that you can handle every particle as it is alone in space and sum up all the contributions from each particle to a given point.
