If a p-n junction diode is in reversed bias

Draw the experimental circuit arrangement for studying V-I characteristics of a p-n junction diode in forward and reverse bias.

(a) Explain with the help of suitable diagram , the two processes which occur during the formations of a p -n junction diode . Hence , define the terms : (i) depletion region and (ii) potential barrier : (b) Draw a circuit diagram of a p - n junction diode under forward bias and explain its working .

When a p-n junction diode is forward biased how will its barrier potential affected
