If the voltage across the diode in the given circuit is $0.5 \ V$,then the current flowing through the circuit is ...... $mA$.

In the following diode circuits,which diode is in a forward-biased condition?

In the given figure,a diode $D$ is connected to an external resistance $R = 100 \,\Omega$ and an $e.m.f.$ of $3.5 \,V$. If the barrier potential developed across the diode is $0.5 \,V$,the current in the circuit will be ........ $mA$.

Assuming that the junction diode is ideal, the current in the arrangement shown in the circuit diagram is (in $ mA$)

$A$ $2\,V$ battery forward biases a diode. There is a drop of $0.5\,V$ across the diode which is independent of current. Also,a current greater than $10\,mA$ produces large joule heat and damages the diode. If the diode is to be operated at $5\,mA$,the series resistance to be used is:

If a $p-n$ junction diode is in forward bias,then:
