Extracted text: 5. For a Zener network shown in Fig. Q5, RS = 4002, Izmin =1 mA, PzMax = 300 mW, Vz = 15V and Vi = 40V. (a) Find the minimum and maximum values of RL So that a regulated constant output voltage is obtained. (b) For the same circuit, if a constant RL= 1KN is connected, then find the range of unregulated D.C voltage source. ww out (UNREGULATED D.C.) Fig.Q5
