The figure represents a voltage regulator circuit using a Zener diode. The breakdown voltage of the Zener diode is 6 V and the load resistance is, RL = 4 kΩ. The series resistance of the circuit is Ri = R = 1 kΩ. If the battery voltage VB varies from 8 V to 16 V, what are the minimum and maximum values of the current through the Zener diode?

0.5 mA; 6 mA
2
1 mA; 8.5 mA
3
0.5 mA; 8.5 mA
4
1.5 mA; 8.5 mA
