Physics - Semiconductors Question with Solution | TestHub

${\mathrm{i}}_1=\frac{14}{1\times {10}^3}=14 \mathrm{mA}$

${\mathrm{i}}_3=\frac{10}{5\times {10}^3}=2 \mathrm{mA}$

${\mathrm{i}}_2={\mathrm{i}}_1-{\mathrm{i}}_3=12 \mathrm{mA}$

Power consumed in zener diode

$=\mathrm{V}\times \mathrm{i}=0.12 \mathrm{W}=120 \mathrm{mW}$
