Question 48: Semiconductors and Logic Gates

Question

A Zener diode of breakdown voltage $$10 \mathrm{~V}$$ is used as a voltage regulator as shown in the figure. The current through the Zener diode is :

Accepted Answer

Zener is in breakdown region.
$$\begin{aligned}
& I_3=\frac{10}{500}=\frac{1}{50} \\
& I_1=\frac{10}{200}=\frac{1}{20} \\
& I_2=I_1-I_3 \\
& I_2=\left(\frac{1}{20}-\frac{1}{50}ight)=\left(\frac{3}{100}ight)=30 \mathrm{~mA}
\end{aligned}$$
