1. The problem statement, all variables and given/known data I have a problem where I need to calculate vo (i.e. output noise) and VO (i.e. DC output voltage) different resistances in a circuit with a Zener diode. The diode is reversed biased but I don't know the Vz. I have the IV curve but can't seem to wrap my head around how to calculate the load line for the Zener diode. Could someone give me some basic steps on calculating the load line and operating point, so I can calculate Vz? 2. Relevant equations Unsure 3. The attempt at a solution I have tried calculating the Thevenin voltage and resistance but still cannot get the load line correct as all the equations I have seen use the current through the diode to calculate the voltage and it doesn't make sense to me. I appreciate any help. Thank you.
