In the given circuit what is the maximum value of $R_S$ for zener diode to regulate voltage on load resistance ?.......$K\Omega $
A
$2$
B
$5$
C
$6$
D
$4$
Solution
For maximum value of $\mathrm{R}_{\mathrm{S}}$ we consider just break down condition.
$\mathrm{I}_{\mathrm{in}} \mathrm{R}_{\mathrm{s}}=24 \Rightarrow \mathrm{R}_{\mathrm{s}}=\frac{24}{6 \times 10^{-3}} \Rightarrow \mathrm{R}_{\mathrm{s}}=4 \mathrm{\,k} \Omega$
