Vedclass · Answer

(C) $1$. Analyze the biasing of each diode:- Diode $D_1$ is forward-biased because its p-side is connected to the positive terminal of the battery.- Diode $D_2$ is in an open circuit (due to the gap in the wire), so no current flows through it. It acts as an unbiased diode.- Diode $D_3$ is reverse-biased because its n-side is connected to the positive terminal of the battery.$2$. Relate bias to depletion width:- Forward bias reduces the depletion width $(W_f - Unbiased state has a standard depletion width $(W_0)$.- Reverse bias increases the depletion width $(W_r > W_0)$.$3$. Compare the widths:- For $D_1$ (forward-biased): $W_1$ is minimum.- For $D_2$ (unbiased): $W_2$ is intermediate.- For $D_3$ (reverse-biased): $W_3$ is maximum.Therefore, $W_3 > W_2 > W_1$.

Three identical p-n junction diodes $D_1$, $D_2$ and $D_3$ are connected across a battery as shown in the figure. If the widths of the depletion regions of $D_1$, $D_2$ and $D_3$ are $W_1$, $W_2$ and $W_3$, respectively, then the correct option is:

Which diode is in forward bias?

Barrier potential of a $p-n$ junction diode does not depend on:

$A$ $2V$ battery is connected across the points $A$ and $B$ as shown in the figure. Assuming that the resistance of each diode is zero in forward bias and infinity in reverse bias,the current supplied by the battery when its positive terminal is connected to $A$ is........$A$

Both the diodes used in the circuit shown are assumed to be ideal and have negligible resistance when these are forward biased. The built-in potential in each diode is $0.7\; V$. For the input voltages shown in the figure,the voltage (in $Volts$) at point $A$ is
