2. The attempt at a solution
So, I know that you can test a Diode with a ohmmeter.
Based off of the R you get Very large reversed biased and fairly low forward biased. But I don't know why it would show these values.
The Large one, revered biased. Kinda makes sense to me since it would have to have a large current to breakdown the diode. potentially...? I'm not quite sure really.
Since Rd is generally about 7ish Ohms, I assume both have to do with the internal current required to drive the diode.
any ideas would be helpful, THX
