Physics - Semiconductors Question with Solution | TestHub

Manufacturers supply a zener diode with zener voltage ${\mathrm{V}}_{\mathrm{z}}=5.6\mathrm{V}$ and maximum power dissipation ${\mathrm{P}}_{\mathrm{z}\max }=\frac{1}{4}\mathrm{W}$. 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 ${\mathrm{V}}_{\mathrm{in}}=10\mathrm{V}$.
