For a Zener diode shunt regulator, the source current is IS, the Zener diode current is IZ and the load current is IL. The source voltage is VS, Zener voltage is VZ and load voltage is VL. The load resistance is RL. What is the correct option for the safe operation of the diode? Correct Answer IS =< IZmax + IL

For proper operation, the current through RS should be at least equal to the sum of IZmin a specified load current. IS >= IZmin + IL For safe operation of the diode, IS =< IZmax + IL.
