Hi:
I have been given a question to answer in a weeks time, but don't have a clue how to answer it.
Question:
Determine the minimum and maximum loads currents for which the zener diode on the figure below will maintain regulation. What is the minimum RL that can be used.
Vz=12v, Izk=3mA and Izm=90mA
Please see attached image file.
I know a zener diode allows current and voltage in both directions. The way this power source is connected is forward biased. Izk appears to be going in reverse bias.
If anyone is up to a challenge, please help guide me through this.
thank you
