The device used for voltage regulation is

$A$ 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?

$A$ Zener diode of breakdown voltage $20 \ V$ is connected as shown in the given circuit. The current through the Zener diode is (in $mA$)

$A$ Zener diode is to be used as a voltage regulator. Identify the correct setup.

When a Zener diode is used as a regulator with a Zener voltage of $10 \, V$, nearly five times the load current passes through the Zener diode. What should be the series resistance for the Zener diode if the load resistance is $2 \, k\Omega$ and the unregulated voltage supplied is $16 \, V$?

Take the breakdown voltage of the zener diode used in the given circuit as $6\, V$. For the input voltage shown in the figure below, the time variation of the output voltage is: (Graphs drawn are schematic and not to scale)
