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

In the given circuits,which diode is in forward bias?

$A$ $p-n$ junction diode is connected to a battery of emf $5.7 \ V$ in series with a resistor of $5 \ k\Omega$ such that it is forward biased. If the barrier potential of the diode is $0.7 \ V$,neglecting the diode resistance,the current in the circuit is:

$A$ potential barrier of $0.50 \ V$ exists across a $P-N$ junction. If the depletion region is $5.0 \times 10^{-7} \ m$ wide,the intensity of the electric field in this region is:

In a semiconductor diode,the $P$-side is earthed and the $N$-side is put at a potential of $-2\,V$. The diode shall
