The forward biased diode connection is

The given circuit has two ideal diodes connected as shown in the figure. The current flowing through the resistance $R_1$ will be

Depletion layer in a p-n junction consists of

A $2\mathrm{V}$ 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

In Figure, ${\mathrm{V}}_{\mathrm{o}}$ is the potential barrier across a $\mathrm{p}-\mathrm{n}$ junction, when no battery is connected across the junction
