In the given circuit,the value of $I_{L}$ (in $mA$) will be: (in $.5$)

Which of the following semi-conducting devices is used as a voltage regulator?

$A$ Zener diode having a breakdown voltage of $5.6 \ V$ is connected in reverse bias with a battery of emf $10 \ V$ and a resistance of $100 \ \Omega$ in series. The current flowing through the Zener diode is (in $mA$)

$A$ 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
