Norton's theorem simplifies any complex linear electrical network into a single current source (In) in parallel with a single resistor (Rn), making circuit analysis easier, especially when analyzing various loads connected to the network. Developed by Hans Ferdinand Mayer and Edward Norton, it's the dual of Thevenin's theorem and applies to linear components (resistors, sources) by replacing the network with a simple equivalent, showing the current it delivers and its internal resistance. #onlin
