In the given circuit, the breakdown voltage of the Zener diode is $3.0 \, V$. What is the value of $I_z$ (in $ \, mA$)?

In the given circuit,the current through the zener diode is ...... $mA$.

For the given circuit (shown in part $(A)$), the time-dependent input voltage $v_{in}(t)$ and the corresponding output voltage $v_{o}(t)$ are shown in part $(B)$ and part $(C)$, respectively. Identify the components that are used in the circuit between points $X$ and $Y$.

In a Zener regulated power supply, a Zener diode with $V_z = 6 \, V$ is used for regulation. The load current is $4 \, mA$ and the unregulated input voltage is $10 \, V$. To get a Zener current five times the load current, the value of the series resistor $R_S$ is nearly:

$A$ 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 ...... $mA$.

If the voltage between the terminals $A$ and $B$ is $17\ V$ and the Zener breakdown voltage is $9\ V$,then the potential voltage across $R$ is.......$V$.
