The $V-I$ characteristic of a diode is shown in the figure. The ratio of forward to reverse bias resistance is

The $\text{I-V}$ characteristic of a $\text{P-N}$ junction in forward bias is shown. The approximate forward resistance of the junction is $-$ (in $\Omega$)

In the circuit shown in the figure,determine the voltage $V_0$ for the circuit network.

If a $p-n$ junction is forward biased,then which of the following figures gives the correct direction of current inside the semiconductor?

The circuit has two oppositely connected ideal diodes in parallel. What is the current flowing in the circuit (in $A$)?

The figure shows a circuit in which three identical diodes are used. Each diode has a forward resistance of $20\,\Omega$ and an infinite backward resistance. Resistors $R_1 = R_2 = R_3 = 50\,\Omega$. The battery voltage is $6\,V$. The current through $R_3$ is.....$mA$.
