A zener shunt regulator employs a zener diode for which VZ = 10.1 V at IZ = 10 mA while rz = 20 Ohm.The available supply voltage (VS) is 15 V, R = 200 Ohm, and the load resistance (RL) = 1.0 k a) Find VZ0. b) Calculate the output voltage (VO) (hint: The derived expression for VO can be used here without proof) c) If RL is changed so that the load current (IL) is increased to 20 mA, what is the value of the output voltage (VO)?
