Question 56: Semiconductors and Logic Gates

Question

In the given circuit, the breakdown voltage of the Zener diode is $$3.0 \mathrm{~V}$$. What is the value of $$\mathrm{I}_{\mathrm{z}}$$ ?

Accepted Answer

$$\mathrm{V}_{\mathrm{z}}=3 \mathrm{~V}$$
Let potential at $$\mathrm{B}=0 \mathrm{~V}$$
Potential at $$E\left(V_Eight)=10 V$$
$$\begin{aligned}
& V_C=V_A=3 V \
& I_z+I_1=I \
& I=\frac{10-3}{1000}=\frac{7}{1000} A \
& I_1=\frac{3}{2000} A
\end{aligned}$$
Therefore $$I_z=\frac{7-1.5}{1000}=5.5 \mathrm{~mA}$$
