Hello, I've got a problem I simply can't get my head around. Basically I need to determine the OP of the Z-Diode through graphical solution. Thus I need the graph of the Z-Diode (which we drew by hand with help of some measured values) and the graph of the equivalent circuit.

Well, I also measured the OP for the Z-Diode with the given circuit, which is

**15,35mA**and

**3,24V**.

With my calculated equivalent circuit graph, there is no interception at those values, not even close.

One basically needs to find the no-load voltage and the short-circuit current to draw a characteristic line of the equivalent circuit.

I got

**3,827V**for the voltage source and

**18mA**for the current. With these values I would get an OP for the Z-Diode of ~5mA and 2,8V which is bullocks.
