In the simple voltage regulator circuit shown in

Figure P9.53, R must maintain the Zener diode current

within its specified limits for all values of the source

voltage, load current, and Zener diode voltage. If

V_{z} = 12 V ± 10%, r_{z} = 9 Ω

i_{z min} = 3.25 mA , i_{z max} = 80 mA

V_{S} = 25 ± 1.5 V

I_{L} = 31.5 ± 21.5 mA

determine the minimum and maximum values of R

which can be used
