Zener breakdown occurs in a $p-n$ junction having $p$ and $n$ both :

$A$ Zener diode is specified as having a breakdown voltage of $9.1 \;V$,with a maximum power dissipation of $364 \;mW$. What is the maximum current $(mA)$ the diode can handle?

The following diagram shows a Zener diode as a voltage regulator. The Zener diode is rated at $V_Z = 5 \text{ V}$ and the desired current in the load is $5 \text{ mA}$. The unregulated voltage source can supply up to $25 \text{ V}$. Considering the Zener diode can withstand four times the load current, the value of resistor $R_S$ (shown in the circuit) should be . . . . . . $\Omega$. (in $\text{ } \Omega$)

What will be the current flowing through the $6 \text{ k}\Omega$ resistor in the circuit shown, where the breakdown voltage of the Zener diode is $6 \text{ V}$?

What is the value of output voltage $V_0$ in $V$ for the circuit shown in the figure?

$A$ Zener diode with a breakdown voltage of $15 \ V$ is used as a voltage regulator. In the circuit shown,the current flowing through the Zener diode is ...... $mA$.
