The figure represents a voltage regulator circuit using a Zener diode. The breakdown voltage of the Zener diode is$6\mathrm{ }\mathrm{V}$and the load resistance is,${\mathrm{R}}_{\mathrm{L}}=4\mathrm{ }\mathrm{k}\mathrm{\Omega }$. The series resistance of the circuit is${\mathrm{R}}_{\mathrm{i}}=1\mathrm{ }\mathrm{k}\mathrm{\Omega }$. If the battery voltage${\mathrm{V}}_{\mathrm{B}}$varies from$8\mathrm{ }\mathrm{V}\mathrm{ }$to$\mathrm{ }16\mathrm{ }\mathrm{V}$, what are the minimum and maximum values of the current through Zener diode?
