In the circuit shown,if the forward voltage drop for the diode is $0.5\, V$,the current in the circuit will be.....$mA$.

The $I-V$ characteristic of a $p-n$ junction diode is shown in the figure. Find the approximate dynamic resistance of the $p-n$ junction when a forward bias of $1 \text{ V}$ is applied. (in $\Omega$)

The potential barrier in a $p-n$ junction diode is due to

In the given circuit,two ideal diodes are connected in parallel in opposite directions. What is the current $I$ flowing in the circuit (in $A$)?

$A$ $2 \text{ V}$ battery is connected to a diode in forward bias. $A$ voltage of $0.5 \text{ V}$ is dropped across the diode,which is independent of the current flowing through it. $A$ current greater than $10 \text{ mA}$ causes excessive heating and damages the diode. If a current of $5 \text{ mA}$ is required in the diode,what value of series resistance must be connected in the circuit?

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