In the circuit diagram shown in the figure,the current through the zener diode is (in $mA$)

In the circuit shown, what will be the current through the $6 V$ zener diode?

In the given circuit,what is the maximum value of $R_S$ (in $k\Omega$) for the Zener diode to regulate the voltage across the load resistance $R_L$?

In the diagram shown,the Zener diode has a reverse breakdown voltage of $V_Z$. The current through the load resistance $R_L$ is $I_L$. The current through the Zener diode is

$A$ voltage regulating circuit consisting of a Zener diode, having a breakdown voltage of $10 \ V$ and a maximum power dissipation of $0.4 \ W$, is operated at $15 \ V$. The approximate value of the protective resistance in this circuit is . . . . . . $\Omega$.

The circuit shown below is working as an $8\; V\; dc$ regulated voltage source. When $12 \; V$ is used as input, the power dissipated (in $mW$) in each diode is (considering both zener diodes are identical).
