Design a zener shunt regulator to provide an output voltage ofapproximately 10V. The supply is a 20V± 20% source andthe load current varies from 0 to 20mA. The zener availablefor use is a 1 watt zener with Vz=10.2V at Iz=20mA and rz=10Ω. Design for aminimum zener current of 5mA.
(A) What is the largest value of R that can be used in thecircuit?
(B) What is the largest zener current(Iz) that willoccur for worst case load currents?
(C) What power does the zener have to dissipate under theseworst case conditions?
(D)Are the ratings of the zener exceeded?
