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 $I_z=\frac{7-1.5}{1000}=5.5 \mathrm{~mA}$
