• A. p-region to n-region
• B. n-region to p-region
• C. n-regionto p-regionwhen forward biased and vice-versa when reverse biased
• D. p-regionto n-regionwhen forward biased and vice-versa when reverse biased

Answer 1

Answer: (B)

n-region to p-region

Answer 2

Diffusion current always flow p to n side.
