I have this circuit:
Assuming that the knee current is 0.2 mA and that the Zener voltage at current 5 mA is 7V. I would like to find the voltage across the load. I am however confused with the question since I assumed that the voltage across a Zener diode cannot go above it's Zener voltage, i.e. 7V, even if the answer of this question is 7.12 V. How come?
