Hi,
I am looking for a formal proof of Thevenin theorem. Actually the first point to clarify is why any linear network seen from a port is equivalent to a linear bipole.
In other words look at the following picture: each of the two parts are networks of bipoles themselves.
Why the part 1 -- as...
So I've been absolutely stumped on this one. I've tried about a million different things but none of them have seemed right. A combination of the odd layout of the circuit, and a combined voltage/current source are making things really complicated for me. I'm somewhat sure the RTh is 15kΩ due to...
Summary:: Trying to find Rth but I do not get the same value as the one from the solution.

I am trying to find Rth to solve this problem, however once I simplified it, I get a value of 700.745 Ω while in the solution, the answer is...
I am having a hard time solving this. Letting \$i\$ be the current flowing into ##R_3##, ##i_1## the current flowing through ##R_1## and ##i_2## the current through ##R_1##—and the node between R3 and R1 be e_1;
Using KVL and KCL, I've managed to find that
##i + I = i_1 + i_2##
Hence...
I have no problem getting the ##R_{TH}## since from the special element's POV, the resistors are in parallel, and that's the answer.
However, I don't really understand how to get ##V_{TH}##.
Ignoring the special element, it seems that I have the resistors in series this time. But I'm not too...
Hi,
after calculations I end up in the circuit below¨ (Thevenin equivalent)
So now I have to say Rth=RL and I will find Rx ?The initial circuit is this:

How do I do Thevenin voltage and impedance with a dependent source? Any hints would be greatly appreciated.
This really isn't one specific problem per se as it is more of a conceptual issue, so I apologize for breaking away from the given format.
I've worked through three problems involving a circuit where a thevenin equivalence circuit is required between two points, and all sources are dependent...

For the linear circuit shown, given that the current I in the 0.9 K\Omega is
10mA when Vs = 100V:
(a) Predict I using the proportionality property for: Vs = 25V, -12V, and 145 V respectively.
(b) Use Thevenin’s theorem across terminals a and b. Find I in terms of Vs and...
