Question

Consider the circuit shown in the figure below:

The output curve of $V_{out}$ versus $I_{in}$ can be represented as

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

For $I_{in}>0,D_1$ wil be ON and $V_{out}=I_{in}{R}_1$.
For $I_{in}<0,D_2$ will be ON and all the current will flow through $D_2$. Since there will be no current flowing through resistance $R_1$. Thus $V_{out}=0$.
