$A$ Zener diode of breakdown voltage $10 \, V$ is used as a voltage regulator as shown in the figure. The current through the Zener diode is (in $ \, mA$)

$A$ Zener diode voltage regulator operated in the range $120 \, V - 180 \, V$ produces a constant supply of $110 \, V$ and $250 \, mA$ to the load. If the maximum current is equally shared between the load and the Zener diode, then the values of load resistance $(R_L)$ and series resistance $(R_S)$ are respectively

In a Zener diode,the reverse bias voltage is $3 \ V$ and the width of the depletion region is $300 \ \mathring{A}$. The electric field intensity will be $\dots \ V/cm$.

$A$ Zener diode of power rating $1.6\,W$ is to be used as a voltage regulator. If the Zener diode has a breakdown voltage of $8\,V$ and it has to regulate an input voltage fluctuating between $3\,V$ and $10\,V$, the value of series resistance $R_s$ for the safe operation of the diode will be $.........\Omega$.

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

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