1. The problem statement, all variables and given/known data We have Vz=6.8 V and Iz=5 mA,rz=20 Ohm,Izk=0.2 mA, R=200 Ohm and the source V= 9 volt a)Find the output voltage when we have the input voltage with the nominal value of 9 Volt. b)Find for the nominal value of the voltage,which is the maximum load current for which the diode works in the breakdown region? c)Find the smallest value of the voltage source for which the diode still works in the breakdown region,while in the charge flows 1/2 of the maximum load current. How do I do this? 2. Relevant equations I have included them in the solution 3. The attempt at a solution Solution for the first one a)http://i.imgur.com/Jgn1bWN.jpg b)http://i.imgur.com/wJYLCAG.jpg c) I dont know how to do this Are my solutions correct? Can you give me a clue on how to do c?
