SUMMARY

The forum discussion centers on understanding the proof of Thevenin's theorem, specifically referencing the method outlined in the Sadiku textbook. The user seeks clarification on the validity of placing an independent current source in the circuit where the load was previously connected to derive the equation V = Vth + I*Rth. The discussion highlights the connection to the substitution theorem as a formal proof method for Thevenin's theorem.

Hello.
Uh, I'm trying to undestand how to prove Thevenin's theorem. The Sadiku book puts an independent current source where the load used to be in order to reach the equation: V = Vth + I*Rth. I do understand how he reaches that conclusion after putting the source, what I don't understand is why he can put that current source where the load was. Could someone explain to me that? I'm not sure if that is a formal proof, but it is a correct way of proving it, then I wish to learn it.

Nevermind, you prove it by using the substitution theorem...
