Zener breakdown in a semiconductor diode occurs when

The Zener diode is used for

Find the current through the Zener diode in the given circuit. (in $mA$)

The $I-V$ characteristics of an electronic device are shown in the figure. The device is $:-$

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

$A$ Zener diode of breakdown voltage $V_{Z} = 8\,V$ and maximum Zener current $I_{ZM} = 10\,mA$ is subjected to an input voltage $V_{i} = 10\,V$ with a series resistance $R = 100\,\Omega$. In the given circuit,$R_{L}$ represents the variable load resistance. The ratio of the maximum and minimum value of $R_{L}$ is
