-(a) Open circuit\\
-(b) 10 kΩ\\
-(c ) 1 kΩ\\
-(d) 100Ω\\
 . Replace the load R<sub>L</sub> with a 5KΩ potentiometer, and adjust the potentiometer to determine the minimum value of R<sub>L</sub> for which V<sub>L</sub> remains within 10% of the zener voltage V<sub>Z</sub>. Measure and report the resistance you set the potentiometer to. How does this resistance relate to the value of R<sub>S</sub>?
