In the following circuit,the reading of the ammeter will be (Take Zener breakdown voltage $= 4 \ V$) (in $mA$)

Manufacturers supply a zener diode with zener voltage $V_{z}=5.6 \, V$ and maximum power dissipation $P_{z \max }=\frac{1}{4} \, W$. This zener diode is used in the following circuit. Calculate the minimum value of the resistance $R_s$ in the circuit so that the zener diode will not burn when the input voltage is $V_{in}=10 \, V$. (in $\Omega$)

The figure represents a voltage regulator circuit using a Zener diode. The breakdown voltage of the Zener diode is $6\,V$ and the load resistance is $R_L = 4\,k\Omega.$ The series resistance of the circuit is $R_i = 1\,k\Omega.$ If the battery voltage $V_B$ varies from $8\,V$ to $16\,V,$ what are the minimum and maximum values of the current through the Zener diode?

The reverse breakdown voltage of a Zener diode is $5.6\, V$ in the given circuit. The current $I_z$ through the Zener is......$mA$
