Calculate the current in the zener with no load (that is, the load current is zero).
The final answer that I got is .2923 A
-The process I used to retrieve the answer is:
Since there is no load connected, using the linear approximation equation above, I rearranged it to get:
Iz = (Vs -Vz0) / (R + rz)
Iz = (10V - 6.2V) / (11.5 + 1.5)
Iz = 3.8/13
Iz = .2923 A
Want to make sure this is correct as I asked this question and an expert gave me a different answer. Can you please explain as much as you can when answering. I really want to understand. THANKS!!
