Thevenin & Norton's practical uses

[swbevz]

Could anyone give me the practical uses for Thevenins and Nortons Theorems have looked through many electrical books but only theoretical and not practical uses if anyone can help it would be much appreciated.

Thanks

Both theorems are usefull for electrical calculations. They offer a quite interesting way to simplify circuit diagrams allowing to reach partial solutions in the selected zones to be analized. For example: Their application allows for the fault currents calculation in a point provided that the equivalent Thévenin or Norton are known. Julian

These thereoms are used daily by circuit designers. Remember designers only make up a small part of electrical engineers. If you will be doing any circuit design or troubleshooting then these thereoms will come in handy.

Thevenin is thee most used theroem in all of circuit design. It reduces any circuit, no matter how complex, to a real generator, with it's characteristic internal impedance. It is used to determine how different loads will effect a signal source output. It is also used in transmission line drive calculations. It is also used to determine how long it will take a digital signal to go down a bus or a backplane. Learn it, and keep it in the front of your forehead.

If you drop a cresent wrench across a car battery and measure the voltage at the instant of contact, is it zero?
If so, why?

Suggestion: The Thevenin's and Norton's Theorems are applicable to the linear circuits only. The nonlinear circuits are often approximated first before the Theorems are applied. Also, the nonlinear circuits exhibit harmonics that somewhat complicate equivalent circuits and their simplifications by these Theorems.
