Stuck on a homework question in my Solid State Electronics class. I've come up with an answer just not certain it's right and wanted to get a second opinion to see if i'm performing calculations correctly. The question is...
Determine the minimum input voltage required for regulation to be established in Figure 3-68. Assume and Ideal zener diode with Izk=1.5mA and Vz=14V
The answer i've come up with is 14.84V
and the second half of the question is....
Repeat above problem with Zz=20Ω and Vz=14V at 30mA.
I made several attempts at the second one with no luck. So I finally looked in the back of the book for the answer which is 14.3V. And again i've tried several times yet cannot come up on my own with an answer of 14.3V. Any help, tips or pointers would be very much appreciated
