Visit the ebooks here on DC Network Analysis.Now to find Vth I just need to find the voltage on the branch where the 200Omh resistor and the 6V battery are.
What is the source of that answer?The answer is Vth=2/3Vin-2 and I can find out why
There are several ways to find Vth. In this case, you might use superposition.View attachment 106669
I have manage to find the Rth=200/3

Vth=2/3Vin-2What is the source of that answer?
You can't find out why because it's NOT true or you typed it incorrectly.
Nothing is wrong with it as I just re-examined the schematic.What's wrong with it?
I was wondering if perhaps you might have been looking at a different port than I was -- the TS wasn't too clear on what he was doing.Nothing is wrong with it as I just re-examined the schematic.
I suspect the TS mean to imply he can't find out why the answer was correct. In my first view, I had the batter polarity reversed when I said the answer was incorrect, but WBahn's posting reminded me to pay closer attention.The answer is Vth=2/3Vin-2 and I can find out why
It goes as far as a perfect diode and not one step further. But for a first "cut" as what to expect, who knows. What we don't know is if the TS had drawn the diode characteristic curve in their labs. We don't know a lot about the TS's studies and labs. All we have is the diagram and a member interpreted question.I am wondering how long a linear analysis will be applied to this non-linear circuit.
As long as the diode is not part of the circuit that the Thevenin equivalent is modeling, it is every bit as valid as not using a Thevenin equivalent at all. We do this all the time. For instance, reducing a biasing network to it's Thevenin equivalent and using that to determine the operating point of a transistor circuit.It goes as far as a perfect diode and not one step further.
