When a $p-n$ junction diode is forward biased,

In a $P-N$ junction under reverse bias,the depletion layer contains .......

To make a $PN$ junction conducting,

Statement $I :$ When a $Si$ sample is doped with Boron,it becomes $P$-type and when doped by Arsenic it becomes $N$-type semiconductor such that $P$-type has excess holes and $N$-type has excess electrons.
Statement $II$ : When such $P$-type and $N$-type semiconductors are fused to make a junction,a current will automatically flow which can be detected with an externally connected ammeter.
In the light of above statements,choose the most appropriate answer from the options given below.

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

For the given circuit of a $PN-$ junction diode,which of the following statements is correct?
