A voltage regulator circuit uses a Zener diode that exhibits a total voltage of 6.8 V at 5 mA. The resistance Rz = 20 O. The supply voltage V+ is nominally 10 V but can vary by ±1.5 V, and the resistance R = 0.5 kO (use the regulator circuit diagram given in class).
a) Find VL (voltage across load resistance) for RL = 2 kO and V+ at its nominal value and the current through the Zener diode (specify direction in your diagram).
b) Find the change in Vo resulting from the ±1.5 V change in V+.
d) What is the minimum value of RL for which the diode operates in the breakdown region?
