I'm trying to understand how to theoretically derive the equation that could be used for plotting the I-V graph. The points of interest are
Out + and
Out - and the current that would flow through that branch if different loads were applied.
I know that the graph should roughly resemble the image below:
After learning that Thevenin can only be used on linear circuits, I got left without ideas.
Is it possible to theoretically approach this and have a function
u_out(i_out) as a result?
