1.	In V.I characteristics of a p-n. junction diode, why is the current under revere bias almost independent of the applied potential upto a critical voltage?
Answer» When a p-n junction is reverse biased, A very small current (of the order of few µA) flows due to drifting of minority charge carriers whose number density remains constant upto the critical voltage. As a result of it, The current under a reverse bias is almost independent of the applied potential upto critical voltage.

Answer»

When a p-n junction is reverse biased,

A very small current (of the order of few µA) flows due to drifting of minority charge carriers whose number density remains constant upto the critical voltage.

As a result of it,

The current under a reverse bias is almost independent of the applied potential upto critical voltage.
