Consider a simple zener voltage regulator with the circuit diagram shown in Figure (a).
(a) For a small reverse resistance RZ << RS and VS - RS iout > VZ, show that vout = VZ.
(b) For values of VS = 25 V, RS = 100 , VZ = 20 V, and RZ = 4 , find:
(i) vout for iout = 0 and iout = 50 mA.
(ii) The corresponding values of the reverse current iZ through the zener diode.
