Zener breakdown takes place if

What will be the current flowing through the $6 \text{ k}\Omega$ resistor in the circuit shown, where the breakdown voltage of the Zener diode is $6 \text{ V}$?

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

$A$ Zener diode in the circuit shown has a knee current of $5\,mA$ and a maximum allowed power dissipation of $300\,mW$. What are the minimum and maximum load currents that can be drawn safely from the circuit, keeping the output voltage $V_0$ constant at $6\,V$?

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 $\Omega$)

What is the value of output voltage $V_0$ in $V$ for the circuit shown in the figure?
