Question:
A circuit is arranged as shown in figure. The output voltage $V_{0}$ is equal to ....... V.
Solution:
As diodes $D_{1}$ and $D_{2}$ are in forward bias, so they acted as neligible resistances
$\Rightarrow$ Input voltage become zero
$\Rightarrow$ Input current is zero
$\Rightarrow$ Output current is zero
$\Rightarrow \mathrm{V}_{0}=5$ volt
