Question

When a forward bias is applied to a $p-n$ junction, it

• A. None of the above
  
• B. reduces the majority carrier current to zero.
  
• C. raises the potential barrier.
  
• D. lowers the potential barrier.
  

Answer 1

The correct option is D lowers the potential barrier.


When a forward bias is applied to a $p-n$ junction, it lowers the value of potential barriers. In the case of a forward bias, the potential barrier opposes the applied voltage. Hence, the potential barrier across the junction gets reduced.

(C) is the correct option.

Final Answer: (𝒄)
