The current in the circuit will be:

$A$ $2 \text{ V}$ 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?

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

In which figure,the junction diode is forward biased?

In the case of forward biasing of a $PN-$ junction,which one of the following figures correctly depicts the direction of flow of majority charge carriers?

When a silicon $PN$ junction is in forward biased condition with a series resistance,it has a knee voltage of $0.6\, V$. The current flowing through it is $5\, mA$ when the $PN$ junction is connected to a $2.6\, V$ battery. The value of the series resistance is.....$\Omega$.
