Question 59: Semiconductors and Logic Gates

Question

If each diode has a forward bias resistance of $$25 ~\Omega$$ in the below circuit,

Which of the following options is correct :

Accepted Answer

$$
\begin{aligned}
& \mathrm{R}_{\mathrm{eq}}=\frac{150 	imes 150}{300}+25=100 \Omega \\
& \mathrm{I}_1=\frac{5}{10}=0.05 \mathrm{~A} \\
& \mathrm{I}_2=\mathrm{I}_4=\frac{0.05}{2}=0.025 \mathrm{~A} \\
& \frac{\mathrm{I}_1}{\mathrm{I}_2}=2
\end{aligned}
$$

Answer

$$\frac{I_{3}}{I_{4}}=1$$

Answer

$$\frac{\mathrm{I}_{1}}{\mathrm{I}_{2}}=2$$

Answer

$$\frac{I_{2}}{\mathrm{I}_{3}}=1$$

Answer

$$\frac{I_{1}}{I_{2}}=1$$
