The zener diode has the following specifications: IZK = 3 mA, IZM = 100 mA. What is the minimum allowable magnitude of RL?

what is Izk and Izm?.. pls help out.. appreciate very much. THANK YOU!

Hi,
Search the e-books & reference data here & you should find most of what you need,

Izk is the knee current of the zener diode. When the current flowing into the zener is larger than the specified knee current, it will permit significant current flow in the reverse direction.

Izm is the maximum zener current the diode can handle without breaking. It is often found by dividing the power rating (Pz) by the breakdown voltage (Vz).

Hopefully that clears up any confusions.
